LTC4357 - Positive High Voltage Ideal Diode Controller

Description

The LTC®4357 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode.

When used in diode-OR and high current diode applications, the LTC4357 reduces power consumption, heat dissipation, voltage loss and PC board area.

Features

  • n Reduces Power Dissipation by Replacing a Power Schottky Diode with an N-Channel MOSFET n 0.5µs Turn-Off Time Limits Peak Fault Current n Wide Operating Voltage Range: 9V to 80V n Smooth Switchover without Oscillation n No Reverse DC Current n Available in 6-Lead (2mm × 3mm) DFN and 8-Lead MSOP Packages.
