LTC4359 - Ideal Diode Controller

General Description

The LTC®4359 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.

Key Features

  • n Reduces Power Dissipation by Replacing a Power Schottky Diode n Wide Operating Voltage Range: 4V to 80V n Reverse Input Protection to.
  • 40V n Low 9µA Shutdown Current n Low 150μA Operating Current n Smooth Switchover without Oscillation n Controls Single or Back-to-Back N-Channel MOSFETs n Available in 6-Pin (2mm × 3mm) DFN, 8-Lead MSOP and 8-Lead SO Packages n AEC-Q100 Qualified for Automotive.
