The LTC4362 is a 1.2A overvoltage/overcurrent protector that includes an internal 40mΩ N-channel MOSFET and 31mΩ current sense resistor in series with the input power supply. The internal avalanche rated MOSFET can absorb a single pulse avalanche energy of 10mJ, eliminating the need for an input capacitor or TVS in most applications. High overvoltage threshold accuracy of 2% and fast shutdown within 1μs protects low voltage electronics from damage. In addition, the LTC4362 monitors the voltage drop across an internal current sense resistor to provide a 20% accurate, 1.5A overcurrent threshold. The input can also withstand up to ±25kV of ESD (HBM) with a 1µF capacitor on the output. Offered in a small 8-pin 2mm x 3mm DFN package, the LTC4362 provides a high level of integration for protecting portable electronics from damage. The LTC4362-1 latches off after an overcurrent event, whereas the LTC4362-2 performs an auto-retry following a 130ms delay.
