Applications
The PLM66100QDCKRQ1 is designed for automotive power-rail redundancy circuits where two supply sources must be ORed together without the forward-voltage drop of Schottky diodes. It is used in ADAS modules, infotainment systems, and body-control units that require seamless failover between battery and regulated supplies operating between 1.5 V and 5.5 V. The SC-70-6 footprint makes it ideal for space-constrained PCB designs within automotive ECUs.

Frequently Asked Questions
What input voltage range does the PLM66100QDCKRQ1 support for automotive power ORing?
The PLM66100QDCKRQ1 operates across an input voltage range of 1.5 V to 5.5 V, covering both 3.3 V and 5 V automotive bus rails. This wide range allows a single component to serve multiple supply domains within an automotive ECU, reducing BOM complexity while ensuring reliable ORing performance in temperatures from -40°C to +125°C.
How does the PLM66100QDCKRQ1 compare to a Schottky diode for power rail redundancy?
A Schottky diode typically drops 0.2 V to 0.4 V at rated current, wasting power and reducing output voltage. The PLM66100QDCKRQ1 uses a P-channel MOSFET switch with very low on-resistance (RDS(on) in the milliohm range), cutting conduction losses to a fraction of the diode loss. This makes it preferable in battery-powered automotive systems where every milliwatt of efficiency matters.
Is the PLM66100QDCKRQ1 suitable for ADAS module designs, and what qualification does it hold?
Yes, the PLM66100QDCKRQ1 is AEC-Q100 qualified for automotive applications, making it appropriate for ADAS modules, body-control units, and infotainment power rails. It is rated for extended temperature operation and complies with automotive reliability standards. The 6-pin SC-70 package measures approximately 2.0 mm × 2.1 mm, fitting tight PCB layouts inside compact ECU housings.
