What are the key features of PLM74801QDRRRQ1?
- Automotive-grade AEC-Q100 ideal diode controller operating from 3 V to 65 V input, covering 12 V and 24 V vehicle battery rails with robust fault protection
- Drives back-to-back N-channel FETs to create a bidirectional ideal diode with near-zero forward voltage drop, dramatically reducing power loss versus Schottky diodes
- Adjustable fault detection threshold and 12-pin SON package enabling compact, tunable reverse-polarity and overvoltage protection in space-constrained automotive ECU designs
What is PLM74801QDRRRQ1 used for?
The PLM74801QDRRRQ1 is used in automotive body control modules and infotainment systems to protect against reverse battery connection and load dump transients across the 3 V to 65 V operating range. It drives back-to-back NFETs as an ideal diode switch in multi-battery or dual-voltage automotive architectures, minimizing voltage drop and heat compared to conventional diode-based solutions. Its AEC-Q100 qualification makes it suitable for under-hood and dashboard power management circuits in passenger vehicles and light commercial trucks.

Frequently Asked Questions
What input voltage range does PLM74801QDRRRQ1 support and which automotive battery systems does that cover?
The PLM74801QDRRRQ1 operates from 3 V to 65 V, covering both 12 V standard automotive batteries and 24 V heavy-vehicle or truck systems, and it also handles load-dump transients above 40 V without damage, making it versatile for a wide range of vehicle power architectures.
How does driving back-to-back NFETs with PLM74801QDRRRQ1 reduce power loss compared to a Schottky diode?
A Schottky diode in a 10 A path drops approximately 0.3–0.5 V, dissipating 3–5 W; the PLM74801QDRRRQ1-driven NFET pair can achieve on-resistance below 5 mΩ per MOSFET, cutting forward drop to under 0.1 V at the same current and reducing power loss by over 60%.
Is PLM74801QDRRRQ1 certified for automotive use, and what qualification standard applies?
Yes, the PLM74801QDRRRQ1 meets AEC-Q100 Grade qualification for automotive integrated circuits, ensuring it has passed the stress tests and reliability requirements for use in passenger-car and light-truck electronic control units operating across the -40°C to 125°C temperature range.
How does the adjustable threshold feature of PLM74801QDRRRQ1 help in a dual-battery 12 V / 48 V mild-hybrid design?
The adjustable threshold allows engineers to set the exact voltage level at which the controller switches the back-to-back FETs on or off, preventing unwanted current flow during 48 V bus startup transients while still conducting normally at steady-state 48 V, which a fixed-threshold device in the same 3 V–65 V range could not tune for.
