AP2141D_1009 Datasheet, PDF (1/17 Pages) Diodes Incorporated – 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE

AP2141D/AP2151D
0.5A SINGLE CHANNEL CURRENT-LIMITED POWER
SWITCH WITH OUTPUT DISCHARGE
Description
Pin Assignments
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-8-EP, and
DFN2018-6 packages.
