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
