Description

The AP2331 is single channel current-limited integrated high-side

power switches optimized for hot-swap applications. The devices

have fast short-circuit response time for improved overall system

robustness and provide a complete protection solution for application

subject to heavy capacitive loads and the prospect of short circuit. It

offers reverse-current blocking, over-current, over-temperature and

short-circuit protection, as well as controlled rise time and under-

voltage lockout functionality.

The device is available in SOT23 and SC59 packages.
