The LTC4359HDCB#TRMPBF 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 across the MOSFET 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 ideal diode controller features a wide operating voltage range of 4V to 80V and can withstand reverse input voltage down to -40V. It has a low operating current of 150µA and a shutdown current of 9µA. The device is designed for applications requiring reduced power consumption, heat dissipation, and voltage loss compared to traditional Schottky diodes.
The LTC4359HDCB#TRMPBF is suitable for demanding automotive and telecom applications. It supports smooth switchover without oscillation and can control single or back-to-back N-channel MOSFETs. The controller is available in a 6-DFN (2x3) package, suitable for surface mounting.
Key features include AEC-Q100 qualification for automotive applications, making it ideal for automotive battery protection, redundant power supplies, and supply holdup. It also finds use in telecom infrastructure, computer systems/servers, and solar systems.
