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.

FEATURES
■ Reduces Power Dissipation by Replacing a Power Schottky Diode
■ Low Quiescent Current: 5µA Operating, 0.5µA Shutdown
■ Wide Operating Voltage Range: 2.5V to 80V
■ Reverse Supply Protection to –28V
■ High Side External N-Channel MOSFET Drive
■ Drives Back-to-Back MOSFETs for Inrush Control and Load Switching
■ Fast Reverse Current Turn-Off within 1.5µs
■ 8-Lead MSOP and 3mm × 3mm DFN Packages

APPLICATIONS
■ Automotive Battery Protection
■ Redundant Power Supplies
■ Portable Instrumentation
■ Solar Powered Systems
■ Energy Harvesting Applications
■ Supply Holdup
