The LTC4372/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. 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 the UVOUT pin provides hysteresis adjustment and status information. During undervoltage, the back-to-back MOSFETs are cut off and quiescent current reduces to 0.5μA.
