0.2A SINGLE CHANNEL

CURRENT-LIMITED LOAD

SWITCH



DESCRIPTION

The UTC US301 is single channel current-limited integrated

high-side power switches, optimized for hot-swap applications.

The US301 provides a complete protection solution for

application subject to heavy capacitive loads and the prospect of

short circuit. The devices have fast short-circuit response time for

improving overall system robustness, and offer reverse-current

blocking, over-current and over-temperature protection, as well as

under-voltage lockout functionality. It also has controlled built-in

soft-start time, typically 0.7 ms.


