US301中文资料0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH数据手册UTC规格书

描述 Description

The UTC  US301 is single channel current-limited integratedhigh-side power switches, optimized for hot-swap applications.  The  US301 provides a complete protection solution forapplication subject to heavy capacitive loads and the prospect ofshort circuit. The devices have fast short-circuit response time forimproving overall system robustness, and offer reverse-currentblocking, over-current and over-temperature protection, as well asunder-voltage lockout functionality. It also has controlled built-insoft-start time, typically 0.7 ms.
