AP2337 Datasheet, PDF (1/10 Pages) Diodes Incorporated – 1.0A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH

AP2337
1.0A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH
Description
The AP2337 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 package.
