Description

General part information

LTC4372 Series

The LTC4372/LTC4373are 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.A 5μA operating current achieves high efficiency for intermittent load applications or always-on backup power supplies. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. The LTC4372/LTC4373 control back-to-back N-channel MOSFETs for inrush current control and load switching.The LTC4372’s SHDN pin keeps the MOSFET off and reduces the quiescent current to 3.5μA. The LTC4373 has a UV pin for undervoltage monitoring while theUVOUTpin provides hysteresis adjustment and status information. During undervoltage, the back-to-back MOSFETs are cut off and quiescent current reduces to 0.5μA.APPLICATIONSAutomotive Battery ProtectionRedundant Power SuppliesPortable InstrumentationSolar Powered SystemsEnergy Harvesting ApplicationsSupply Holdup
