LTC4376 7A Ideal Diode with Reverse Input Protection FEATURES DESCRIPTION n Reduces Power Dissipation by Replacing a Power The LTC 4376 is a 7A ideal diode that uses an internal Schottky Diode 15m N-channel MOSFET to replace a Schottky diode n Wide Operating Voltage Range: 4V to 40V when used in diode-OR and high current diode applica- n Internal 15m N-Channel MOSFET tions. The LTC4376 reduces power consumption, heat n Reverse Input Protection to 40V dissipation and PC board area. n Low 9A Shutdown Current The LTC4376 controls the forward voltage drop across n Low 150A Operating Current the internal MOSFET to ensure smooth current delivery n Smooth Switchover without Oscillation without oscillation even at light loads. If a power source n Available in 16-Pin 5mm 4mm DFN Package fails or is shorted, a fast turn-off minimizes reverse cur- n AEC-Q100 Qualified for Automotive Applications rent transients. The LTC4376 also easily ORs power sources to increase total system reliability. APPLICATIONS With its low operating voltage, small solution size and the n Automotive Battery Protection ability to withstand reverse input voltage, the LTC4376 n Redundant Power Supplies excels in portable battery applications. A shutdown mode n Portable Battery Devices is available to reduce the quiescent current to 9A. The n Computer Systems/Servers 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.
