LTC4354 - Negative Voltage Diode-OR Controller/Monitor

General Description

The LTC®4354 is a negative voltage diode-OR controller that drives two external N-channel MOSFETs.

It replaces two Schottky diodes and the associated heat sink, saving power and area.

Key Features

  • n Controls N-Channel MOSFETs n Replaces Power Schottky Diodes n Less Than 1µs Turn-off Time Limits Peak Fault Current n 80V Operation n Smooth Switchover without Oscillation n No Reverse DC Current n Fault Output n Selectable Fault Thresholds n Available in 8-Lead (3mm × 2mm) DFN and 8-Lead SO Packages.
