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.
