AP2181D Datasheet, PDF (1/18 Pages) Diodes Incorporated – 1.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE
AP2181D/AP2191D
1.5A SINGLE CHANNEL CURRENT-LIMITED POWER
SWITCH WITH OUTPUT DISCHARGE
Description
Pin Assignments
The AP2181D and AP2191D 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 over-current reporting and
does not require any external components.
All devices are available in SO-8, MSOP-8, MSOP-8-EP,
SOT25, and DFN2018-6 packages.
