LTC4370CDE#PBF

LTC4370 is a two-supply current sharing controller which incorporates MOSFET ideal diodes. The diodes block reverse and shoot-through currents during start-up and fault conditions. Their forward voltage is adjusted to share the load currents between supplies. Unlike other sharing methods, neither a share bus nor trim pins on the supply are required. The maximum MOSFET voltage drop can be set with a resistor. A fast gate turn-on reduces the load voltage drop during supply switchover. 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, high availability systems and servers, telecom and network infrastructure etc.
