Diodes Incorporated Single-Chip Switch for VBUS Line Protection

Diodes Incorporated AP22953 Single-Chip Switch is designed for USB 2.0/3.0/Type-C connector VBUS line protection. The AP22953 Bidirectional MOSFET Switch provides normal current flow in both charging and host mode while protecting the internal circuits from overvoltage conditions at the V_{BUS_CON} pin. On the V_{BUS_CON} pin, the device has overvoltage protection of up to 30V. After the #EN pin is pulled low, the AP22953 counts 20ms before turning on the MOSFET via soft-start delay. The #ACK pin indicates the MOSFET is fully turned ON.

The Diodes Inc AP22953 Single-Chip Switch typical application interface is the VBUS line in USB connectors. Typical end equipment for the AP22953 includes smartphones, tablet PCs, wearables, and electronic-point-of-sale (EPOS) systems. The AP22953 can also be used with other devices that use a 5V power rail interface.

Overtemperature protection turns off the switch at 145°C (typical). The AP22953 is offered in the wafer level chip scale W-WLB2013-12 1.988mm x 1.288mm x 0.64mm package with backside laminate.
