AP2181D/AP2191D
1.5A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISCHARGE
Description
The AP2181D and AP2191D are integrated high-
side power switches
optimized for Universal Serial Bus (USB) and other hot-
swap
applications. The f
amily 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 capa
bility
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-8, MSOP-
8EP, SOT25, and
U-DFN2018-6 packages.
