描述

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. The circuit breaker current level (ICB) for each rail is set by two external resistors, and for each rail a delay (tCB) is set by an external capacitor on the TCB pin. After tCB has expired, the IC then quickly pulls down the associated GATE(s) output turning off its external FET(s).
