SWITCH FOR VBUS LINE WITH OVERVOLTAGE, SURGE, AND ESD PROTECTION

Description

Pin Assignments

The AP22953 device is a single-chip solution for USB 2.0/3.0/Type-C

connector VBUS line protection. The bidirectional MOSFET switch

ensures 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 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.

AP22953

The typical application interface for the AP22953 is the V_BUSline in

USB connectors. Typical end equipment for the AP22953 include

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.
