Revision 1.07 Page 10 of 19 SLGC55544CV USB Charging Port Power Switch and Controller ©2022 Renesas Electronics Corporation Overview The following overview references various industry standards. It is always recommended to consult the most up-to-date standard to ensure the most recent and accurate information. Rechargeable portable equipment requires an extern al power source to charge its batteries. USB ports are a convenient lo cation for charging because of an available 5 V pow er source. Universally accepted standards are required to make sure host a nd client-side devices operate together in a system to ensure power management requirements are met. Traditionally, USB host ports following the USB 2.0 specification must provide at least 500 mA to downstream client-side devices. Because multiple USB devices can be attached to a single USB port through a bus-powered hub, it is the responsibility of the client-side device to negotiate its power allotment from the host to ensure the total current draw does not exceed 500 mA. In general, each USB device is granted 100 mA and may request more current in 100 mA unit steps up to 500 mA. The host may grant or deny based on the available current. Additionally, the success of USB has made the mini- USB connector a popular choice for wall adapter cab les. This allows a portable device to charge from both a wall adapter and USB port with only one connector. One common di fficulty has resulted from this. As USB charging has gained popularity, t he 500 mA minimum defined by USB 2.0 has become ins ufficient for many handset and personal media players which need a higher charging rate. On the other hand, wall adapters can provide much more current than 500 mA. Several new standards have been introduced defining protocol handshaking methods that allow host and client devices to acknowledge and draw additional c urrent beyond the 500 mA minimum defined by USB 2.0 while still using a single micro-USB input connector. The SLGC55544CV supports three of the most common protocols:

USB 2.0 Battery Charging Specification BC1.2
Chinese Telecommunications Industry Standard YD/T 1591-2009
Divider Mode All three methods have similarities and differences , but the biggest commonality is that all three def ine three types of charging ports that provide charging current to client-side devices. These charging ports are defined as:
Standard Downstream Port (SDP)
Charging Downstream Port (CDP)
Dedicated Charging Port (DCP) BC1.2 defines a Charging Port as a downstream facing USB port that provides power for charging portable equipment. The table below shows the differences between these ports according to BC1.2 (draft). BC1.2 (draft) defines the protocol necessary to allow portable equipment to determine what type of port it is connected to so that it can allot its maximum allowable current draw. The hand-shaking process has two steps. During step one, the primary detection, the portable equipment outputs a nominal 0.6-V output on its D+ line and reads the voltage input on its D- line. The portable device concludes it is connected to an SDP if the voltage is less than the nominal data detect voltage of 0.3 V. The portable device concludes that it is connected to a Charging Port i f the D- voltage is greater than the nominal data d etect voltage of 0.3 V and less than 0.8 V. The second step, the secondary detection, is necessary for portable equipment to determine between a CDP and a DCP. The portable device outputs a nominal 0.6 V output on its D- line and reads the voltage input on its D+ line. The portable device concludes it is connected to a CDP if the data line being read remains less than the nominal data detect voltage of 0.3 V. The portable device concludes it is connected to a DCP if the data line being read is greater than the nominal data detect voltage of 0.3 V and less than 0.8 V. Operating Modes Port Type Supports USB 2.0 Communication Maximum Allowable Current Draw By Portable Equipment (A) SDP (USB 2.0) Yes 0.5 SDP (USB 3.0) Yes 0.9 CDP Yes 1.5 DCP No 1.5

Revision 1.07 Page 11 of 19 SLGC55544CV USB Charging Port Power Switch and Controller ©2022 Renesas Electronics Corporation Standard Downstream Port (SDP) An SDP is a traditional USB port that follows USB 2.0/3.0 and supplies a maximum of 500 mA per port for USB 2.0 and 900 mA per port for USB 3.0. USB 2.0 communications is supported, and the host controller must be active to allow charging. Charging Downstream Port (CDP) be active to allow charging. What separates a CDP from an SDP is the host-charge handshaking logic that identifies this port as a CDP . A CDP is identifiable by a compliant BC1.2 (draft) client device and allows for additional current draw by the client device. The CDP hand-shaking process is two steps. During step one the portable equipment outputs a nominal 0.6 V output on its D+ line and reads the voltage input on its D- line. The portable device concludes it is connected to an SDP if the voltage is less than the nominal data detect voltage of 0.3 V. The portable device concludes that it is connected to a Charging Port if the D- voltage is greater than the nominal data detect voltage of 0.3V and less than 0.8 V. The second step is necessary for portable equipment to determine between a CDP and a DCP . The portable device outputs a nominal 0.6 V output on its D- line and reads the voltage input on its D+ line. The portable device concludes it is connected to a CDP if the data line being read remains less than the nominal data detect voltage of 0.3 V. The portable device concludes it is connected to a DCP if the data line being read is greater than the nominal data detect voltage of 0.3 V and less than 0.8 V. Dedicated Charging Port (DCP) A DCP is a special type of wall-adapter used in charging applications that uses a micro-B connector to connect to portable devices. A DCP only provides power and does not support data connection to an upstream port. As shown in follow ing sections, a DCP is identified by the electrical characteristics of its data lines. The SLGC55544CV emulates DCP in two charging states, namely DCP Forced and DCP Auto. In DCP Forced state the device will support one of the following two DCP charging schemes: Divider1 or Shorted. In DCP Auto state, the SLGC55544CV char ge detection state machine is enabled which will se lectively implement charging schemes involved with the Shorted, Divider1, Divider2, and 1.2 V modes. Shorted DCP mode complies with BC1.2 and Chinese Telecommunications Industry Standard YD/T 1591-2009, Divider and 1.2V modes are used to charge devices that do not comply with BC1.2 DCP standard. High-Bandwidth Data Line Switch The SLGC55544CV passes the D+ and D- data lines through the device to enable monitoring and handshaking while supporting charging operation. A wide bandwidth signal switch is used, allowing data to pass through the device w ithout corrupting signal integrity. The data line switches are turned on in any of CDP or SDP operating modes. The EN input als o needs to be at logic High for the data line switches to be enabled. Note: 1. While in CDP mode, the data switches are ON even while CDP handshaking is occurring. 2. The data line switches are OFF if EN is low, or if in DCP mode (BC1.2 (draft), Divider mode or Auto -detect). They are not automatically turned off if the power switch (VIN to VOUT) is doing current limiting. With SLGC55544CV, the data line switches are also off when in “000” mode. 3. The data switches are for USB 2.0 differential pair only. In the case of a USB 3.0 host, the super speed differential pairs must be routed directly to the USB connector without passing through the SLGC55544CV. Logic Control Modes The SLGC55544CV supports the listed standards above for the SDP , CDP and DCP modes using the CTL1, CTL2, and CTL3 logic I/O control pins, although their truth tables are different as shown below. The different CTLx s ettings correspond to the different types of charge modes. Also, using the Auto-Detect Mode, the Divider Mode or BC1.2 (draft) / YD/T 1591-2009 can be automatically selected without external user interaction Note: With the SLGC55544CV, if the “000” mode is selected , the power switch will be turned off and an output discharge resistor will be connected, while the data line switches will be turned off.

Revision 1.07 Page 13 of 19 SLGC55544CV USB Charging Port Power Switch and Controller ©2022 Renesas Electronics Corporation Wake On USB The SLGC55544CV supports low and full speed HID (hu man interface device like mouse/keyboard) wake func tion. There are two scenarios under which wake on mouse are support ed by the SLGC55544CV. The specific CTL pin changes that the SLGC55544CV will override are shown below. The information is presented as CTL1, CTL2, CTL3. The ILIM_SEL pin plays no role. 1. 111 (CDP/SDP2) to 011 (DCP-Auto) 2. 010 (SDP1) to 011 (DCP-Auto) Note that the 110 (SDP1) to 011 (DCP-Auto) transiti on is not supported. This is done for practical rea sons since the transition involves changes to two CTL pins. Depending on which CTL pin changes first, the device will see either a temporary 111 or 010 command. The 010 command is safe but the 111 comman d will cause an OUT discharge as the SLGC55544CV wi ll instead proceed to the 111 state. Output Discharge To allow a charging port to renegotiate current wit h a portable device, SLGC55544CV uses the VBUS disc harge function. It proceeds by turning off the power switch while discharging VOUT, then turning back ON the power switch to reassert the VOUT voltage. This discharge function is automatically a pplied when a change at the CTLx lines results in a ny of the following mode transitions.

Any transition to and from CDP
Any transition to and from SDP In addition to this, can be achieved using the mode “000”. Overcurrent Protection When an over-current condition is detected, the dev ice maintains a constant output current and reduces the output voltage accordingly. Two possible overload conditions can occur. In the first condition, the output has been shorted before the device is enabled or before VIN has been applied. The SLGC55544CV senses the short and immediately switches into a constant-current output. In the second condition, a short or an overload occurs while the device is enabled. At the instant the overload occurs, high currents m ay flow for nominally one to two microseconds before the current-limit circuit can react. The device operates in constant-current mode after the current-limit circuit has responded. Complete shutdown occurs only if the fault is present long enough to activate thermal limiting. The device will remain off until the junction temperature cool s approximately 10°C and will then re-start. The de vice will continue to cycle on/off until the over-current condition is removed. FAULT# Response The FAULT# open-drain output is asserted (active low) during an over-temperature or current limit condition. The output remains asserted until the fault condition is removed. The SLGC55544CV is designed to eliminate false FAULT# r eporting by using an internal deglitch circuit for current limit conditi ons without the need for external circuitry. This e nsures that FAULT# is not Trans-State Time Transition From Transition To Discharge Time (Typ.)

Revision 1.07 Page 14 of 19 SLGC55544CV USB Charging Port Power Switch and Controller ©2022 Renesas Electronics Corporation accidentally asserted due to normal operation such as starting into a heavy capacitive load. Over-temperature conditions are not deglitched and assert the FAULT# signal immediately. Undervoltage Lockout (UVLO) The undervoltage lockout (UVLO) circuit disables th e power switch until the input voltage reaches the UVLO turn-on threshold. Built-in hysteresis prevents unwanted oscillations on the output due to input voltage drop from large current surges. Thermal Sense The SLGC55544CV protects itself with two independen t thermal sensing circuits that monitor the operati ng temperature of the power distribution switch and disables operation if the temperature exceeds recommended operating cond itions. The device operates in constant-current mode during an over-current condition, which increases the voltage drop across power switch. The power dissipation in the package is proportional to the voltage drop across the power switch, so the j unction temperature rises during an over-current condition. The first thermal sensor turns off the power switch when the die tem perature exceeds 135 °C and the part is in current limit. The second thermal sensor turns off the power switch when the die temperature exceeds 155 °C regardless of whether the power switch is in curren t limit. Hysteresis is built into both thermal sens ors, and the switch turns on after the device has cooled by approximately 10 °C. The switch continues to cycle off and on until the fault is removed. The open-drain false reporting output FAULT# is asserted (active low) during an over-temperature shutdown condition. Application and Layout Guidelines

The designed power supply range is from 4.5 V to 5.5 V. If the input supply is located more than a few inches from the device, an input bypass capacitor larger than 0.1 µF is recommended.
The trace routing from the upstream regulator to t he VIN pin must be as short as possible to reduce the voltage drop and parasitic inductance.
The trace routing from the Current-Limit Set Resis tors to the device must be as short as possible to reduce parasitic effects on Current-Limit accuracy.
