AP2141/ AP2151
0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2141 and AP2151 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. They 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.
All devices are available in SO-8, MSOP-8EP, SOT25 and U-
DFN2018-6 packages.
