DETAILED DESCRIPTION
Undervoltage and Overvoltage Comparators and Logic
When the comparators detect that VCC is within the operating window, the GATE output is driven high to turn
on the external N-channel MOSFET. When VCC goes above the set overvoltage level, or below the set
undervoltage level, the GATE output is driven low.
Charge pump
An internal charge pump supplies power to the GATE drive circuit and provides the necessary voltage to pull
the gate of the MOSFET above the source.
Zener Diodes
Limit internal power rails to 8.0 V and GATE output to 18 V.
Shut-Off MOSFET
When an undervoltage or overvoltage event occurs, this MOSFET is turned on to pull down the gate of the
external N-channel MOSFET, thus isolating the load from the incoming transient.
