ADI LTC4359IDCB#WTRPBF

Контроллер N+1 ORingN-канальный220 мкА

Overview

The LTC4359IDCB 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 LTC4359IDCB 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 LTC4359IDCB satisfies the demanding requirements of both automotive and telecom applications. The LTC4359IDCB also easily ORs power sources in systems with redundant supplies.
