- Adjustable threshold with single-channel input fault protection controller function for flexible overcurrent and reverse-battery protection system design
- AEC-Q100 automotive qualified in 12-pin WSON (S-PDSO-N12) package, introduced May 2020, meeting stringent automotive reliability and temperature requirements
What is PLM74800QDRRRQ1 used for?
The PLM74800QDRRRQ1 is designed for automotive power distribution systems requiring reverse polarity protection, ideal diode ORing, and input fault protection in 12V to 48V vehicle electrical architectures. Its 65V maximum input voltage makes it suitable for 48V mild hybrid systems, where back-to-back NFET control reduces power losses compared to conventional diode solutions. The device is also applicable in body control modules, battery management systems, and automotive load switches requiring protection against reverse battery connection and voltage transients.

Frequently Asked Questions
What is the input voltage range of the PLM74800QDRRRQ1?
The PLM74800QDRRRQ1 supports an input voltage range from 3V to 65V, making it compatible with standard 12V, 24V, and 48V automotive electrical architectures. This wide range allows it to handle automotive transients and load dump events common in vehicle power systems while maintaining protection circuit functionality.
Why does the PLM74800QDRRRQ1 use back-to-back NFETs instead of a diode?
The back-to-back N-channel MOSFET configuration driven by the PLM74800QDRRRQ1 acts as an ideal diode with significantly lower forward voltage drop than Schottky diodes — typically below 50mV versus 300-500mV for Schottky devices. This reduces conduction losses and heat generation in automotive power paths, improving overall system efficiency especially in high-current applications.
Is the PLM74800QDRRRQ1 AEC-Q100 automotive qualified?
Yes, the PLM74800QDRRRQ1 is automotive qualified per AEC-Q100 standards, as indicated by the 'Q1' suffix in the part number. It is rated for the temperature and reliability requirements of automotive electronics applications, making it suitable for under-hood and body electronics environments with extended temperature ranges.
What package does the PLM74800QDRRRQ1 use?
The PLM74800QDRRRQ1 comes in a 12-pin WSON (WQSON) no-lead package with JESD-30 code S-PDSO-N12, featuring a square plastic/epoxy body. The small outline no-lead package equivalence code is SOLCC12,.12,20, providing excellent thermal performance and compact PCB footprint suitable for space-constrained automotive ECU designs.
What does the adjustable threshold feature of the PLM74800QDRRRQ1 enable?
The adjustable threshold feature allows designers to set the overcurrent or voltage fault detection level using external resistors, tailoring the protection response to specific load and wiring harness characteristics. This flexibility enables optimization for different automotive subsystems — for example, setting lower current thresholds for sensitive electronics versus higher thresholds for motor loads — without requiring different controller ICs.
