The LTC4359HMS-4#WPBF is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9μA for load switch and 14µA for ideal diode applications.

When used in high current diode applications, the LTC4359HMS8#PBF reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359HMS8#PBF satisfies the demanding requirements of both automotive and telecom applications. The LTC4359HMS8#PBF also easily ORs power sources in systems with redundant supplies.
