LTC4368IMS-2 Product Details

The LTC4368IMS-2 protects applications from power supply voltages that may be too high, too low, or even negative and from overcurrent faults in both forward and reverse directions. The LTC4368IMS-2 controls the gate voltage of a pair of external N-channel MOSFETs to ensure that the load is connected to the input supply only when there are no voltage or current faults.

Two comparator inputs allow configuration of the overvoltage (OV) and undervoltage (UV) set points using an external resistive divider. A current sense resistor sets the forward and reverse circuit breaker current thresholds. After a forward current fault, the LTC4368IMS-2 will either latchoff power, or retry after a user adjustable delay. After a reverse current fault, the LTC4368IMS-2 waits for the output to fall 100mV below the input to reconnect power to the load.

The LTC4368IMS-2 has a 32ms turn-on delay that debounces live supply input connections and blocks 50Hz and 60Hz AC power. UV/OV faults also trigger the 32ms recovery delay before the external MOSFETs are turned back on.
