DESCRIPTION

The LTC®4364 surge stopper with ideal diode controller

protects loads from high voltage transients. It limits and

regulates the output during an overvoltage event, such

as load dump in automobiles, by controlling the voltage

drop across an external N-channel MOSFET pass device.

The LTC4364 also includes a timed, current limited circuit

breaker. In a fault condition, an adjustable fault timer must

expire before the pass device is turned off. The LTC4364-1

latches off the pass device while the LTC4364-2 automatically

restarts after a delay. The LTC4364 precisely monitors

the input supply for overvoltage (OV) and undervoltage

(UV) conditions. The external MOSFET is held off in undervoltage

and auto-retry is disabled in overvoltage.

An integrated ideal diode controller drives a second MOSFET

to replace a Schottky diode for reverse input protection

and output voltage holdup. The LTC4364 controls the

forward voltage drop across the MOSFET and minimizes

reverse current transients upon power source failure,

brownout or input short.
