AP2331 Datasheet, PDF (1/11 Pages) Diodes Incorporated – 0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH

AP2331
0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH
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.
