AP2181A/AP2191A
1.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
Pin Assignments
The AP2181A and AP2191A are integrated high-side power switches
optimized for Universal Serial Bus (USB) and other hot-swap
applications. This family of devices complies with USB 2.0 and is
available with both polarities of Enable input. The AP2181A and
AP2191A offer current and thermal limiting and short circuit protection
as well as controlled rise time and undervoltage lockout functionality.
A 7ms deglitch capability on the open-drain Flag output prevents false
over-current reporting and does not require any external components.
