ISL6174IRZ集成电路（IC）的热插拔控制器规格书PDF中文资料

This IC targets dual voltage hot swap applications across the +2.5V to +3.3V (nominal) bias supply voltage range with a second lower voltage rail down to less than 1V where a circuit breaker response to an over current event is preferred. It features a charge pump for driving external N-Channel MOSFETs, accurate programmable circuit breaker current thresholds and delay output undervoltage monitoring and reporting and adjustable soft-start.
