USB Type-C VBUS Combo Switch with Protection

Overview

The HL5099 provides a dual–channel VBUS power switch and 3.3V low dropout (LDO) for USB power delivery (PD) applications. The device includes a bi–directional high–voltage switch that can support up to 22V sink and 6V source voltage, a VOTG switch supporting up to 13.2V source voltage, and a 100mA 3.3V LDO providing power supply to the PD controller in a dead battery operation.

Additionally, between the VBUS and VCHG, the back-to-back high-voltage switch (HVSW) is implemented, and its absolute maximum rating (AMR) is at 28V for both pins. The integrated power switch can also be configured as a bi-directional switch with an appropriate I²C control or enable pins. In the sink mode, the allowable current is continuous 5A, while in the source mode, the switch current flows from VCHG to VBUS, and maximum allowable current is 3A. From VOTG to VBUS (VOTG mode), there is a back-to-back power switch, which AMR is 16V on VOTG. This switch is to source power from VOTG to VBUS up to 13.2V and 3A continuous current. This power switch has an ideal diode feature and supports fast role swap for USB PD3.0 application.
