Available in 4mm × 3mm 14-Lead DFN, 16-Lead MSOP,
and 16-Lead SO Packages 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 …
