LTC4353 Datasheet - Linear Technology

LTC4353 Dual Low Voltage Ideal Diode Controller

The LTC®4353 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 ho.
