LTC4359IMS8#PBF Description

The LTC4359IMS8#PBF 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 LTC4359IMS8#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 LTC4359IMS8#PBF satisfies the demanding requirements of both automotive and telecom applications. 

The LTC4359IMS8#PBF also easily ORs power sources in systems with redundant supplies.
