Product Overview

The LTC4364HDE-2#PBF is a 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 LTC4364-2 automatically restarts after a delay. It 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. It controls the forward voltage drop across the MOSFET and minimizes reverse current transients upon power source failure, brownout or input short.
  • Withstands surges over 80V with VCC clamp
  • Adjustable output clamp voltage
  • Ideal diode controller holds up output voltage during input brownouts
  • Overcurrent protection
  • Adjustable fault timer
