LTC4359CMS8#TRPBF

LTC4359 is a positive high voltage ideal diode controller with reverse input protection. 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. When used in high current diode applications, the LTC4359 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 LTC4359 satisfies the demanding requirements of both automotive and telecom applications. The LTC4359 also easily ORs power sources in systems with redundant supplies. Typical applications are automotive battery protection, redundant power supplies, supply holdup, telecom infrastructure, computer systems/servers, solar systems.
