ap2171dfm

Manufacturer Part Number
ap2171dfm
Description
1a Single Channel Current-limited Power Switch With Output Discharge
Manufacturer
Diodes, Inc.
Datasheet
The AP2161D and AP2171D 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.
Applications
Description
All devices are available in SOT25, SO-8, MSOP-8-EP, and
DFN2018-6 packages.
