AP2166/ AP2176
1A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2166 and AP2176 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 and under-voltage lockout functionality. A 7ms deglitch capability
on the open-drain Flag output prevents false overcurrent reporting
and does not require any external components.
All devices are available in SO-8 and MSOP-8EP packages.
