The LM66100DCKT is a single-channel ideal diode OR controller from Texas Instruments, integrating a P-Channel MOSFET to replace a Schottky diode in power-ORing and reverse-polarity protection. The 27 µs turn-on delay and 2 µs turn-off delay let it switch between supplies fast enough to prevent rail droop during source transitions.
Industrial temperature grade and SC-70-6 footprint
The SC-70-6 (SOT-363) package occupies roughly 2.0 mm × 2.1 mm, which keeps the PCB footprint tight for space-constrained battery-management or USB-C power-path designs.
