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.
