The LTC4359IMS8#TRPBF is a positive high voltage ideal diode controller from Analog Devices. It drives an external N-channel MOSFET to replace a Schottky diode, controlling the forward voltage drop for 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.
This controller operates over a wide voltage range of 4V to 80V and offers reverse input protection to -40V. It has a low operating current of 220µA and a low shutdown current of 9µA, making it suitable for power-sensitive applications. The device is AEC-Q100 qualified for automotive applications and is available in an 8-MSOP package.
Key applications include automotive battery protection, redundant power supplies, supply holdup, telecom infrastructure, computer systems/servers, and solar systems. It reduces power consumption, heat dissipation, and voltage loss compared to traditional Schottky diodes. The LTC4359 also facilitates easy ORing of power sources in systems with redundant supplies.
