ADI LTC4376HDHD#TRPBF

The LTC4376 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 battery applications. A shutdown mode is available to reduce the quiescent current to 9μA. The SHDN pin can also control the forward current path when an external MOSFET is used in series with the internal MOSFET in a back-to-back configuration.
