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).
