diodes. The diodes block reverse and shoot-through currents during start-up and fault conditions. Their forward voltage is adjusted to share the load currents between supplies. Unlike other sharing methods, neither a share bus nor trim pins on the supply are required. The maximum MOSFET voltage dro...

LTC4371 : The LTC®4371 is a two-input negative voltage ideal diode-OR controller that drives external N-channel MOSFETs as a low dissipation alternative to Schottky diodes.
LTC4372 : 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. 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 turnoff 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. Th.

LTC4376 : The LTC®4376 is a 7A ideal diode that uses an internal 15mΩ N-channel MOSFET to replace a Schottky diode when used in diode-OR and high current diode applications. The LTC4376 reduces power consumption, heat dissipation and PC board area. The LTC4376 controls the forward voltage drop across the internal 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. The LTC4376 also easily ORs power sources to increase total system reliability. With its low operating voltage, small solution size and the ability to withstand reverse input voltage, the LTC4376 excels in portable batte.
