AP2141D/ AP2151D
0.5 SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISCHARGE
Description
The AP2141D and AP2151D 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 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 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.
All devices are available in SOT25, SO-8, MSOP-8EP, and
U-DFN2018-6 packages.
