LTC4372IMS8#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4372IMS8#TRPBF is a positive high voltage ideal diode controller manufactured by Analog Devices Inc. It drives an external N-channel MOSFET to replace Schottky diodes, ensuring current delivery or transfer even at light loads. The device features a wide operating voltage range of 2.5V to 80V and reverse supply protection down to -28V. Key electrical parameters include a quiescent current of 5µA during operation and 0.5µA in shutdown mode. It provides fast reverse current turn-off within 1.5µs. The component operates within a temperature range of -40°C to +85°C and is housed in an 8-lead MSOP package.
