LTC4359CMS8#PBF General Description

The LTC4359 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.

Key Features

Reduces Power Dissipation by Replacing a Power Schottky Diode
Wide Operating Voltage Range: 4V to 80V
Reverse Input Protection to – 40V
Low 9µA Shutdown Current
Low 150μA Operating Current

Application

Automotive Battery Protection
Redundant Power Supplies
Supply Holdup
Telecom Infrastructure
Computer Systems/Servers
Solar Systems
