                                                                                                  LTC4353 is a dual low voltage ideal diode controller. It controls external N-channel MOSFETs to implement an ideal diode function. It replaces two high power Schottky diodes and their associated heat sinks, saving power and board area. The ideal diode function permits low loss power supply ORing and supply holdup applications. This device 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-current transients. It is widely used in application such as redundant power supplies, supply holdup, high availability systems and servers, telecom and network infrastructure etc.
