LTC4373 - Low Quiescent Current Ideal Diode Controller

Download the LTC4373 datasheet PDF. This datasheet also covers the LTC4372 variant, as both devices belong to the same low quiescent current ideal diode controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®4372/LTC4373 are positive high voltage ideal diode controllers that drive an external N-channel MOSFET to replace a Schottky diode.

They control the forward voltage drop across the MOSFET to ensure current delivery or current transfer from one path to the other even at light loads.

Key Features

  • n Reduces Power Dissipation by Replacing a Power Schottky Diode n Low Quiescent Current: 5µA Operating n Wide Operating Voltage Range: 2.5V to 80V n Reverse Supply Protection to.
  • 28V n No TVS Input Clamps Required n High Side External N-Channel MOSFET Drive n Drives Back-to-Back MOSFETs for Inrush Control and Load Switching n Shutdown Input for ON/OFF Control n Fast Reverse Current Turn-Off within 1.5µs n 8-Lead MSOP and 3mm × 3mm DFN Packages.
