AP22953 SWITCH FOR VBUS LINE WITH OVERVOLTAGE, SURGE, AND ESD PROTECTION 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 VBUS_CON pin. On the VBUS_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. The typical application interface for the AP22953 is the VBUS line 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. The AP22953 is available in the wafer level chip scale W-WLB201312 1.988mm x 1.288mm x 0.64mm package with backside laminate. Overtemperature protection turns off the switch at 145°C (typical).
