Docking Stations General Description The MIC20XX family of switches are current limiting, high-side power switches, designed for general purpose power distribution and control in digital televisions (DTV), printers, set top boxes (STB), PCs, PDAs, and other peripheral devices (see MIC20XX Family Package Types and the MIC20XX Family Member Functionality table). MIC20XX family’s primary functions are current limiting and power switching. They are thermally protected and will shutdown should their internal temperature reach unsafe levels, protecting both the device and the load, under high-current or fault conditions. Features include fault reporting, fault blanking to eliminate noise-induced false alarms, output slew rate limiting, under voltage detection, automatic-on output, and enable pin with choice of either active low or active high enable. The FET is self-contained, with a fixed- or user-adjustable current limit. The MIC20XX family is ideal for any system where current limiting and power control are desired. The MIC201X (3 ≤ X ≤ 9) and MIC2019A switches offer a unique new patented feature: Kickstart which allows momentary high-current surges up to the secondary current limit (I LIMIT_2nd) without sacrificing overall system safety. The MIC20XX family is offered, depending on the desired features, in a space-saving 5-lead SOT-23, 6-lead SOT-23, and 2 mm x 2 mm DFN packages.

These pin and signal descriptions aid in the differentiation of a pin from electrical signals and components connected to that pin. For example, VOUT is the switch’s output pin, while VOUT is the electrical signal output voltage present at the VOUT pin. The descriptions of the pins are listed in Table 3-1.

4.0 FUNCTIONAL DESCRIPTION

4.1 V IN and VOUT

VIN is both the power supply connection for the internal circuitry driving the switch and the input (Source connection) of the power MOSFET switch. VOUT is the Drain connection of the power MOSFET and supplies power to the load. In a typical circuit, current flows from VIN to V OUT toward the load. Because the switch is bi-directional when enabled, if VOUT is greater than VIN, current will flow from VOUT to VIN. When the switch is disabled, current will not flow to the load, except for a small unavoidable leakage current of a few microamps. However, should V OUT exceed V IN by more than a diode drop (~0.6V), while the switch is disabled, current will flow from output to input via the power MOSFET’s body diode. If discharging C LOAD is required by your application, consider using MIC20X4 or MIC20X7; these MIC20XX family members are equipped with a discharge FET to be ensured complete discharge of CLOAD.

4.2 Current Sensing and Limiting

MIC20XX protects the system power supply and load from damage by continuously monitoring current through the on-chip power MOSFET. Load current is monitored by means of a current mirror in parallel with the power MOSFET switch. Current limiting is invoked when the load exceeds the set over current threshold. When current limiting is activated the output current is constrained to the limit value, and remains at this level until either the load/fault is removed, the load’s current requirement drops below the limiting value, or the switch goes into thermal shutdown.

4.3 Kickstart

Note: Only parts in bold have Kickstart (Not available in 5-lead SOT-23 packages). The MIC201X is designed to allow momentary current surges (Kickstart) before the onset of current limiting, which permits dynamic loads, such as small disk drives or portable printers to draw the energy needed to overcome inertial loads without sacrificing system safety. In this respect, the Kickstart parts (MIC201X) differs markedly from the non-Kickstart parts (MIC200X) which immediately limit load current, potentially starving the motor and causing the appliance to stall or stutter. During this delay period, typically 128 ms, a secondary current limit is in effect. If the load demands a current in excess the secondary limit, MIC201X acts immediately to restrict output current to the secondary limit for the duration of the Kickstart period. After this time the MIC201X reverts to its normal current limit. An example of Kickstart operation is shown in Figure 4-1: FIGURE 4-1: Kickstart Operation. Figure 4-1 Label Key: A. MIC201X is enabled into an excessive load (slew rate limiting not visible at this time scale). The initial current surge is limited by either the overall circuit resistance and power supply compliance, or the secondary current limit, whichever is less. B. R ON of the power FET increases due to internal heating (effect exaggerated for emphasis). C. Kickstart period. D. Current limiting initiated. FAULT/ goes LOW. E. VOUT is non-zero (load is heavy, but not a dead short where VOUT = 0V. Limiting response will be the same for dead shorts). F. Thermal shutdown followed by thermal cycling. G. Excessive load released, normal load remains. MIC201X drops out of current limiting. H. FAULT/ delay period followed by FAULT/ going HIGH.

4.4 Undervoltage Lockout

Undervoltage lockout ensures no anomalous operation occurs before the device’s minimum input voltage of UVLOTHRESHOLD, which is 2V minimum, 2.25V typical, and 2.5V maximum, has been achieved. Prior to reaching this voltage, the output switch (power MOSFET) is OFF and no circuit functions, such as FAULT/ or ENABLE, are considered to be valid or operative.

4.5 Variable Undervoltage Lockout

Note: Only parts in bold have UVLO. VUVLO functions as an input voltage monitor when the switch in enabled. The VIN pin is monitored for a drop in voltage, indicating excessive loading of the V IN supply. When V IN is less than the V ULVO threshold voltage (VVUVLO_TH) for 32 ms or more, the MIC20XX disables the switch to protect the supply and allow VIN to recover. After 128 ms has elapsed, the MIC20X6 enables switch. This disable and enable cycling will continue as long as V IN deceases below the V UVLO threshold voltage (V VUVLO_TH) which has a typical value of 250 mV. The V UVLO voltage is commonly established by a voltage divider from VIN-to-GND.

4.6 Enable

Note: Only parts in bold have ENABLE pin. ENABLE pin is a logic compatible input that activates the main MOSFET switch thereby providing power to the VOUT pin. ENABLE is either an active HIGH or active LOW control signal. The MIC20XX can operate with logic running from supply voltages as low as 1.5 V. ENABLE may be driven higher than VIN, but no higher than 5.5V and not less than –0.3V.

4.7 Fault/

Note: Only parts in bold have FAULT/ pin. FAULT/ is an N-channel open-drain output that is asserted (LOW true) when switch either begins current limiting or enters thermal shutdown. FAULT/ asserts after a brief delay when events occur that may be considered possible faults. This delay insures that FAULT/ is asserted only upon valid, enduring, over-current conditions and that transitory event error reports are filtered out. In MIC200X FAULT/ asserts after a brief delay period, of 32 ms typical. After a fault clears, FAULT/ remains asserted for the delay period of 32 ms. MIC201X’s FAULT/ asserts at the end of the Kickstart period which is 128 ms typical. This masks initial current surges, such as would be seen by a motor load starting up. If the load current remains above the current limit threshold after the Kickstart has timed out, then the FAULT/ will be asserted. After a fault clears, FAULT/ remains asserted for the delay of 128 ms. Because FAULT/ is an open-drain it must be pulled HIGH with an external resistor and it may be wire-OR’d with other similar outputs, sharing a single pull-up resistor. FAULT/ may be tied to a pull-up voltage source which is higher than VIN, but no greater than 5.5V.

4.8 Soft-Start Control

Large capacitive loads can create significant inrush current surges when charged through the switch. For this reason, the MIC20XX family of switches provides a built-in soft-start control to limit the initial inrush currents. Soft-start is accomplished by controlling the power MOSFET when the ENABLE pin enables the switch.

4.9 C SLEW

4.10 Thermal Shutdown

Thermal shutdown is employed to protect the MIC20XX family of switches from damage should the die temperature exceed safe operating levels. Thermal shutdown shuts off the output MOSFET and asserts the FAULT/ output if the die temperature reaches 145°C. The switch will automatically resume operation when the die temperature cools down to 135°C. If resumed operation results in reheating of the die, another shutdown cycle will occur and the switch will continue cycling between ON and OFF states until the overcurrent condition has been resolved. Depending on PCB layout, package type, ambient temperature, etc., hundreds of milliseconds may elapse from the incidence of a fault to the output MOSFET being shut off. This delay is due to thermal time constants within the system itself. In no event will the device be damaged due to thermal overload because die temperature is monitored continuously by on-chip circuitry.

5.0 APPLICATION INFORMATION

5.1 Setting I LIMIT

The MIC2009/2019’s current limit is user programmable and controlled by a resistor connected between the ILIMIT pin and GND. The value of this resistor is determined by Equation 5-1: EQUATION 5-1: or EQUATION 5-2: For example: Set ILIMIT = 1.25A Please see the Electrical Characteristics table to find CLF at ILIMIT = 1A. For the sake of this example, we will say the typical value of CLF at an I OUT of 1A is 243V. Applying Equation 5-2: EQUATION 5-3: Designers should be aware that variations in the measured ILIMIT for a given R SET resistor, will occur because of small differences between individual ICs (inherent in silicon processing) resulting in a spread of ILIMIT values. In the example above we used the typical value of CLF to calculate R SET. We can determine ILIMIT’s spread by using the minimum and maximum values of CLF and the calculated value of RSET. EQUATION 5-4: Giving us a maximum ILIMIT variation over temperature of:

ILIMIT_MIN = 0.97A (−22%)

5.3 CSLEW

Note: Only parts in bold have CSLEW pin. (Not available in 5-pin SOT-23 packages). The CSLEW pin is provided to increase control of the output voltage ramp at turn-on. This input allows designers the option of decreasing the output’s slew rate (slowing the voltage rise) by adding an external capacitance between the CSLEW and VIN pins. This capacitance slows the rate at which the pass FET gate voltage increases and thus, slows both the response to an enable command as well as V OUT’s ascent to its final value. Figure 5-5 illustrates effect of CSLEW on turn-on delay and output rise time. FIGURE 5-5: CSLEW vs. Turn-On, Delay and Rise Times.

5.3.1 C SLEW’S EFFECT ON ILIMIT

An unavoidable consequence of adding C SLEW capacitance is a reduction in the MIC20X5 - 20X8’s ability to quickly limit current transients or surges. A sufficiently large capacitance can prevent both the primary and secondary current limits from acting in time to prevent damage to the MIC20X5 - 20X8 or the system from a short circuit fault. For this reason, the upper limit on the value of CSLEW is 4 nF.

5.4 Variable Undervoltage Lockout

(VUVLO) Note: Only parts in bold have VUVLO pin and functionality. Power-conscious systems, such as those implementing ACPI, will remain active even in their low-power states and may require the support of external devices through both phases of operation. Under these conditions, the current allowed these external devices may vary according to the system’s operating state and as such require dual current limits on their peripheral ports. The MIC20X6 is designed for systems demanding two primary current limiting levels but without the use of a control signal to select between current limits. To better understand how the MIC20X6 provides this, imagine a system whose main power supply supports heavy loads during normal operation, but in sleep mode is reduced to only few hundred milliamps of output current. In addition, this system has several USB ports which must remain active during sleep. During normal operation, each port can support a 500 mA peripheral, but in sleep mode their combined output current is limited to what the power supply can deliver minus whatever the system itself is drawing. If a peripheral device is plugged in which demands more current than is available, the system power supply will sag, or crash. The MIC20X6 prevents this by monitoring both the load current and V IN. During normal operation, when the power supply can source plenty of current, the MIC20X6 will support any load up to its factory programmed current limit. When the weaker, standby supply is in operation, the MIC20X6 monitors VIN and will shut off its output should V IN dip below a predetermined value. This predetermined voltage is user programmable and set by the selection of the resistor divider driving the VUVLO pin. To prevent false triggering of the VUVLO feature, the MIC20X6 includes a delay timer to blank out momentary excursions below the VUVLO trip point. If VIN stays below the VUVLO trip point for longer than 32 ms (typical), then the load is disengaged and the MIC20X6 will wait 128 ms before reapplying power to the load. If V IN remains below the VUVLO trip point, then the load will be powered for the 32 ms blanking period and then again disengaged. This is illustrated in the scope plot below. If VIN remains above the VUVLO trip point MIC20X6 resumes normal operation. FIGURE 5-6: VUVLO Operation.

 2021 - 2022 Microchip Technology Inc. and its subsidiaries DS20006486C-page 23 MIC20XX VUVLO and Kickstart operate independently in the MIC2016. If the high current surge allowed by Kickstart causes VIN to dip below the VUVLO trip point for more than 32 ms, VUVLO will disengage the load, even though the Kickstart timer has not timed out. FIGURE 5-7: VUVLO Application Circuit.

5.4.1 CALCULATING VUVLO RESISTOR

The VUVLO feature is designed to keep the internal switch off until the voltage on the VUVLO pin is greater than 0.25V. A resistor divider network connected to the VUVLO and VIN pins is used to set the input trip voltage V TRIP (see Figure 5-7). The value of R2 is chosen to minimize the load on the input supply IDIV and the value of R1 sets the trip voltage VTRIP. The value of R2 is calculated using: EQUATION 5-5: The value of R1 is calculated using: EQUATION 5-6: Where for Equation 5-5 and Equation 5-6: VVUVLO = 0.25V When working with large value resistors, a small amount of leakage current from the VUVLO terminal can cause voltage offsets that degrade system accuracy. Therefore, the maximum recommended resistor value for R2 is 100 kΩ. Using the divider loading current I DIV of 100 µA, the value of R2 can be estimated by: EQUATION 5-7: Now the value of R1 can be calculated by: EQUATION 5-8: The VUVLO comparator uses no hysteresis. This is because the VUVLO blanking timer prevents any chattering that might otherwise occur if VIN varies about the trigger point. The timer is reset by upward crossings of the trip point such that VIN must remain below the trip point for the full 32 ms period for load disengagement to occur. In selecting a VTRIP voltage, the designer is cautioned to not make this value less than 2.5V. A minimum of 2.5V is required for the MIC20X6’s internal circuitry to operate properly. VUVLO trip points below 2.5V will result in erratic or unpredictable operation.

5.5 Kickstart

Note: Only parts in bold have Kickstart (Not available in 5-pin SOT-23 packages). Kickstart allows brief current surges to pass to the load before the onset of normal current limiting, which permits dynamic loads to draw bursts of energy without sacrificing system safety. Functionally, Kickstart is a forced override of the normal current limiting function provided by the switch. The Kickstart period is governed by an internal timer which allows current to pass up to the secondary current limit (ILIMIT_2nd) to the load for 128 ms and then normal (primary) current limiting goes into action. During Kickstart, a secondary current-limiting circuit is monitoring output current to prevent damage to the switch, as a hard short combined with a robust power supply can result in currents of many tens of amperes. This secondary current limit is nominally set at 4A and reacts immediately and independently of the Kickstart VIN MIC20X6 VOUT VUVLO Input Supply IIN_LOAD R2 VVUVLO IDIV R1 R2 VTRIP VVUVLO  = TABLE 5-6: KICKSTART 2003 2004 2005X 2006 2007 2008 2009X 2013 2014 2015 2016 2017 2018 2019X R2 0.25V R1 2.5 k 4.75V   45k== Where: VTRIP = 4.75V (for a 5V supply) VVUVLO = 0.25V

DS20006486C-page 24  2021 - 2022 Microchip Technology Inc. and its subsidiaries period. Once the Kickstart timer has finished its count the primary current limiting circuit takes over and holds IOUT to its programmed limit for as long as the excessive load persists. Once the switch drops out of current limiting the Kickstart timer initiates a lock-out period of 128 ms such that no further bursts of current above the primary current limit, will be allowed until the lock-out period has expired. Kickstart may be over-ridden by the thermal protection circuit and if sufficient internal heating occurs, Kickstart will be terminated and IOUT → 0A. Upon cooling, if the load is still present IOUT → ILIMIT, not ILIMIT_2nd. FIGURE 5-8: Kickstart.

5.6 Automatic Load Discharge

Note: Only parts in bold have automatic load dis- charge. Automatic discharge is a valuable feature when it is desirable to quickly remove charge from the VOUT pin. This allows for a quicker power-down of the load. This also prevents any charge from being presented to a device being connected to the VOUT pin, for example, USB, 1394, PCMCIA, and CableCARD. Automatic discharge is performed by a shunt MOSFET from VOUT pin to GND. When the switch is disabled, a break before make action is performed turning off the main power MOSFET and then enabling the shunt MOSFET. The total resistance of the MOSFET and internal resistances is typically 126Ω.

5.7 Supply Filtering

A minimum 1 μF bypass capacitor positioned close to the VIN and GND pins of the switch is both good design practice and required for proper operation of the switch. This will control supply transients and ringing. Without a bypass capacitor, large current surges or a short may cause sufficient ringing on V IN (from supply lead inductance) to cause erratic operation of the switch’s control circuitry. For best-performance good quality, low-ESR capacitors are recommended, preferably ceramic. When bypassing with capacitors of 10 μF and up, it is good practice to place a smaller value capacitor in parallel with the larger to handle the high frequency components of any line transients. Values in the range of 0.01 μF to 0.1 μF are recommended. Again, good quality, low-ESR capacitors should be chosen.

5.8 Power Dissipation

Power dissipation depends on several factors such as the load, PCB layout, ambient temperature, and supply voltage. Calculation of power dissipation can be accomplished by the following equation: EQUATION 5-9: To relate this to junction temperature, the following equation can be used: EQUATION 5-10: In normal operation the switch’s RON is low enough that no significant I 2R heating occurs. Device heating is most often caused by a short circuit, or very heavy load, when a significant portion of the input supply voltage appears across the switch’s power MOSFET. Under these conditions the heat generated will exceed the package and PCB’s ability to cool the device and thermal limiting will be invoked.

The plots also assume a worst case RON of 140 mΩ at a die temperature of 135°C. Under these conditions it is clear that an SOT-23 packaged device will be on the verge of thermal shutdown, typically 140°C die temperature, when operating at a load current of 1.25A. For this reason we recommend using DFN packaged switches for any design intending to supply continuous currents of 1A or more.
