Ideal diode controller with internal 7A FET
The LTC4376HDHD#PBF is a current sharing controller from Analog Devices that integrates an N-Channel MOSFET and the control logic into a single 16-WFDFN package. It operates as an ideal diode — the internal switch replaces a Schottky diode for reverse-input protection and load sharing with a fraction of the forward voltage drop. Rated for 7A continuous output current across a 4V to 40V supply range, the part targets automotive, redundant power supply, portable battery, and computer system applications where OR-ing diodes or load sharing between parallel supplies is needed.
Temperature grade and what it buys you
The 300 ns turn-off delay is fast enough to catch reverse-current transients from a failing input supply before the current builds. The 150 µA quiescent supply current keeps the overhead low in always-on battery-backed rails.
Package and board integration
The exposed paddle is the main thermal path — the datasheet layout recommendation calls for multiple vias to a copper plane. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions for a DFN package.
Sourcing and compliance
ROHS3 compliant per the #PBF suffix.
