Ordering Information

Pin # Pin Name Type Pin Description

1 ON Input

A low-to-high transition on this pin initiates the operation of the SLG59H1008V’s state machine. ON is an asserted HIGH, level-sensitive CMOS input with VIL < 0.3 V and VIH > 0.9 V. As the ON pin input circuit does not have an internal pull-down resistor, connect this pin to a general-purpose output (GPO) of a microcontroller, an application processor, or a system controller – do not allow this pin to be open-circuited. 2G N D G N D Pin 2 is a low-current GND terminal for the SLG59H1008V. Connect directly to Pin 3 3G N D G N D Pin 3 is the main ground connection for the SLG59H1008V’s internal charge pump, its gate drive and current-limit circuits as well as its internal state machine. Therefore, use a short, stout connection from Pin 3 to the system’s analog or power plane. 4-8 VIN MOSFET VIN supplies the power for the operation of the SLG59H1008V, its internal control circuitry, and the drain terminal of the nFET power switch. With 5 pins fused together at VIN, connect a 47 μF (or larger) low-ESR capacitor from this pin to ground. Capacitors used at VIN should be rated at 50 V or higher. 9-13 VOUT MOSFET Source terminal of n-channel MOSFET (5 pins fused for VOUT). Connect a 47 μF (or larger) low-ESR capacitor from this pin to ground. Capacitors used at VOUT should be rated at 50 V or higher.

14 SEL Input

As a low logic-level CMOS input with V IL < 0.3 V and VIH > 1.65 V, SEL selects one of two undervoltage/overvoltage lockout windows. When SEL = LOW, the VIN undervoltage/overvoltage lockout window is set for 12 V ±10% applications. When SEL = HIGH, the VIN undervoltage/overvoltage lockout window is set for 24 V ±5% applications. See the Electrical Characteristics table for additional information.

15 FAULT Output

An open drain output, FAULT is asserted within TFAULTLOW when a VIN undervoltage, VIN overvoltage, a current-limit, or an over-temperature condition is detected. FAULT is deasserted within TFAULTHIGH when the fault condition is removed. Connect an 100 kΩ external resistor from the FAULT pin to local system logic supply.

16 CAP Output

A low-ESR, stable dielectric, ceramic surface-mount capacitor connected from CAP pin to GND sets the VOUT slew rate and overall turn-on time of the SLG59H1008V. For best performance, the range for CSLEW values are 10 nF ≤ CSLEW≤ 20 nF – please see typical characteristics for additional information. Capacitors used at the CAP pin should be rated at 10 V or higher. See equation for selecting capacitor and start-up slewing.

17 IOUT Output

IOUT is the SLG59H1008V’s power MOSFET load current monitor output. As an analog output current, this signal when applied to a ground-reference resistor generates a voltage proportional to the current through the n-channel MOSFET. The I OUT transfer characteristic is typically 10 μA/A with a voltage compliance range of 0.5 V ≤ VIOUT ≤ 4V. Optimal IOUT linearity is exhibited for 0.5 A ≤ IDS ≤ 4 A. In addition, it is recommended to bypass the IOUT pin to GND with a 0.18 nF capacitor.

18 RSET Input

A 1%-tolerance, metal-film resistor between 20 kΩ and 91 kΩ sets the SLG59H1008V’s active current limit. A 91 kΩ resistor sets the SLG59H1008V’s active current limit to 1 A and a 20 kΩ resistor sets the active current limit to 4.5 A.

000-0059H1008-101 Page 11 of 19 SLG59H1008V Applications Information HFET1 Safe Operating Area Explained Silego’s HFET1 integrated power controllers incorporate a number of internal protection featur es that prevents them from damaging themselves or any other circuit or subcircuit downstr eam of them. One particular protection feature is their Safe Operation Area (SOA) protection. SOA pr otection is automatically activated under overpower and, in some cases, under overcurrent conditions. Overpower SOA is activated if package power dissipation exceeds an internal 5W threshold longer than 2.5 ms. HFET1 devices will quickly switch off (open circuit) upon overpower detection and automatically resume (close) nominal operation once overpower condition no longer exists. One possible way to have an overpower condition trigger SOA protection is when HFET1 products are enabled into heavy output resistive loads and/or into large load capacitors. It is u nder these conditions to follow carefully the “Safe Start-up Loading” guidance in the Applications section of the datasheet. During an overcurrent condition, HFET1 devices will try to limit the output current to the level set by the external R SET resistor. Limiting the output current, however, causes an increased voltage drop across the FET’s channel because the FET’s RDS ON increased as well. Since the FET’s RDS ON is larger, package power dissipation also increases. If the resultant increase in package power dissipation is higher/equal than 5 W for longer than 2.5 ms, internal SOA protection will be triggered a nd the FET will open circuit (switch off). Every time SOA protection is triggered, a ll HFET1 devices will automatically attempt to resume nominal operation after 160 ms. Safe Start-up Condition SLG59H1008V has built-in protection to prevent over-heating during start-up into a heavy load. Overloading the VOUT pin with a capacitor and a resistor may result in non-monotonic V OUT ramping. In general, under light loading on VOUT, V OUT ramping can be controlled with CSLEW value. The following equation serves as a guide: where T RISE = Rise time from 10% VOUT to 90% VOUT VIN = Input Voltage CSLEW = Capacitor value for CAP pin When capacitor and resistor loading on VOUT during start up, the following tables will ensure VOUT ramping is monotonic without triggering internal protection: Safe Start-up Loading for VIN = 24 V (Monotonic Ramp) Slew Rate (V/ms) C SLEW (nF)2 CLOAD (μF) R LOAD (Ω) 0.5 66.7 500 80 1.0 33.3 250 80 1.5 22.2 160 80 2.0 16.7 120 80 2.5 13.3 100 80 CSLEW = TRISE VIN x 4.9 μA x 20

Configuring the SLG59H1008V for 12 V VIN Lockout Applications To configure the SLG59H1008V for conditioned 12 V ±10% VIN applications is simply a matter of connecting the SEL pin to GND as shown in Figure A.

24 V VIN and 12 V VIN Lockout Window Thresholds

Shown in Figure B and Figure C are the two sets of VIN overvoltage/undervoltage lockout windows – one for conditioned 24 V ±5% VIN systems and the second for conditioned 12 V ±10% VIN systems. To avoid lockout threshold collision with nominal operation, the SLG59H1008V’s VIN(OVLO) min and V IN(UVLO) max thresholds were set 0.1 V correspondingly higher than the system’s nominal VIN max or lower than the system’s VIN min range. Power Dissipation The junction temperature of the SLG59H1 008V depends on different factors such as board layout, ambient temperature, and other environmental factors. The primary contributor to the increase in the junction temperature of the SLG59H1008V is the power dissipation of its power MOSFET. Its power dissipation and the junction temperature in nominal operating mode can be calculated using the following equations: where: PD = Power dissipation, in Watts (W) RDSON = Power MOSFET ON resistance, in Ohms (Ω) IDS = Output current, in Amps (A) and where: TJ = Junction temperature, in Celsius degrees (°C) θJA = Package thermal resistance, in Celsius degrees per Watt (°C/W) TA = Ambient temperature, in Celsius degrees (°C) Figure B. Figure C. PD = RDSON x IDS TJ = PD x θJA + TA

000-0059H1008-101 Page 14 of 19 SLG59H1008V Power Dissipation (continued) In current-limit mode, the SLG59H1008V’s power dissipation can be calculated by taking into account the voltage drop across the power switch (VIN-VOUT) and the magnitude of the output current in current-limit mode (IACL): where: PD = Power dissipation, in Watts (W) VIN = Input Voltage, in Volts (V) RLOAD = Load Resistance, in Ohms (Ω) IACL = Output limited current, in Amps (A) VOUT = RLOAD x IACL PD = (VIN-VOUT) x IACL or PD = (VIN – (RLOAD x IACL)) x IACL
