1A SINGLE CHANNEL CURRENT-LIMITED

POWER SWITCH WITH OUTPUT DISCHARGE

Description

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 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, MSOP-8EP, and U-DFN2018-6 packages.

Functions

Over-current and over-temperature fault report; open-drain flag is active low when triggered

Exposed pad. It should be connected to GND and thermal mass for enhanced thermal

impedance. It should not be used as electrical ground conduction path.
