0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH

Description

Pin Assignments

The AP2151A is an 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 is available with active

high Enable input. They offer current and thermal limiting and short

circuit protection as well as controlled rise time and under-voltage

lockout functionality. A 7ms deglitch capability on the open-drain Flag

output prevents false over-current reporting and does not require any

external components.
