LT4356-3 Surge Stopper with Fault Latchoff FEATURES DESCRIPTION n ® Stops High Voltage Surges The LT 4356-3 surge stopper protects loads from high n Adjustable Output Clamp Voltage voltage transients. It regulates the output during an n Overcurrent Protection overvoltage event, such as load dump in automobiles, n Wide Operation Range: 4V to 80V by controlling the gate of an external N-channel MOSFET. n Reverse Input Protection to –60V The output is limited to a safe value thereby allowing the n Low 7μA Shutdown Current loads to continue functioning. The LT4356-3 also monitors n Adjustable Latchoff Fault Timer the voltage drop between the VCC and SNS pins to protect n Controls N-channel MOSFET against overcurrent faults. An internal amplifi er limits n Shutdown Pin Withstands –60V to 100V the current sense voltage to 50mV. In either fault condi- n Fault Output Indication tion, a timer is started inversely proportional to MOSFET n Auxiliary Amplifi er for L
