What are the key features of PLM74810QDRRRQ1?
- Dual-channel ideal diode architecture drives back-to-back NFETs for ultra-low forward voltage drop active rectification, replacing Schottky diodes and cutting conduction losses
- Integrated overvoltage switch mode and adjustable input fault protection threshold safeguard downstream loads from load-dump transients in 12 V and 24 V automotive systems
- AEC-Q100 qualified automotive device in a 12-pin SON package (3.5 mm x 3 mm) enabling compact automotive power distribution and ORing designs
What is PLM74810QDRRRQ1 used for?
The PLM74810QDRRRQ1 is designed for automotive power distribution networks where dual redundant supply ORing and reverse current blocking are required to protect electronic loads. It replaces power Schottky diodes in body control modules, gateway ECUs, and server-room power supplies, reducing forward voltage drop from 0.4 V to less than 10 mV and improving overall system efficiency. Its adjustable fault thresholds also make it suitable for industrial power entry modules and 48 V mild-hybrid automotive architectures requiring active input protection.

Frequently Asked Questions
How does PLM74810QDRRRQ1 improve efficiency compared to Schottky diode ORing in a 12 V automotive system?
PLM74810QDRRRQ1 drives back-to-back N-channel MOSFETs with on-resistance as low as a few mΩ, reducing the forward voltage drop from approximately 0.4 V seen with Schottky diodes to less than 10 mV. At a 10 A load current, this can reduce conduction power loss per channel from 4 W to under 0.1 W, substantially improving efficiency in dual-supply automotive ORing applications.
What is the overvoltage switch mode in PLM74810QDRRRQ1 and when is it activated?
The overvoltage switch mode in PLM74810QDRRRQ1 turns off the external NFET pair when the input voltage exceeds an adjustable threshold, protecting downstream loads from load-dump or surge events common in 12 V and 24 V automotive environments. The threshold is set via an external resistor divider, allowing designers to configure protection from approximately 14 V to over 40 V depending on system requirements.
How many channels does PLM74810QDRRRQ1 support and what package does it use?
PLM74810QDRRRQ1 integrates 2 independent ideal-diode controller channels in a 12-pin SON (small-outline no-lead) package with a 3.5 mm x 3 mm footprint. Both channels share a single IC, enabling dual-supply ORing or series back-to-back blocking configurations while consuming minimal PCB area in space-constrained automotive ECU designs.
Which automotive supply standards does PLM74810QDRRRQ1 meet and what temperature range does it cover?
PLM74810QDRRRQ1 is AEC-Q100 Grade 1 qualified, meeting the automotive component reliability standard for junction temperatures from -40°C to 125°C. This qualification makes it acceptable for use in automotive body control modules, telematics units, and gateway ECUs in passenger vehicles produced by tier-1 suppliers following IATF 16949 quality management requirements.
