The is a near-Ideal Diode Controller using an external N-channel MOSFET. It replaces a high power Schottky diode and the associated heat sink, saving power and board area. The LTC4352 regulates the forward voltage drop across the MOSFET to ensure smooth current transfer in diode-OR applications. A fast turn-ON reduces the load voltage droop during supply switch-over. If the input supply fails or is shorted, a fast turn-OFF minimizes reverse currents. Power passage is disabled during undervoltage or overvoltage conditions. The controller also features an open MOSFET detect circuit that flags excessive voltage drop across the pass transistor in the on state. A REV pin enables reverse current, overriding the diode behaviour when desired.
