AP2101/AP2111

2A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH

Description

The AP2101 and AP2111 are integrated high-side power switches

optimized for Universal Serial Bus (USB) and other hot-swap

applications. The family of devices complies with USB 2.0 and

available with both polarities of Enable input. They offer current and

thermal limiting and short circuit protection as well as controlled rise

time, under-voltage lockout and auto-discharge functionalities. A

7ms deglitch capability on the open-drain Flag output prevents false

over-current reporting and does not require any external components.

All devices are available in SO-8 and MSOP-8EP packages.

Features

• Single USB port power switches with auto-discharge

AP2101/AP2111 Application Information Power Supply Considerations A 0.1-μF to 1-μF X7R or X5R ceramic bypass capacitor between IN and GND, close to the device, is recommended. Placing a high-value electrolytic capacitor on the input (10-μF minimum) and output pin(s) is recommended when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01-μF to 0.

AP2101/AP2111 Application Information (cont.) Thermal Protection Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The AP2101/AP2111 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch.
