MPQ3367GR-AEC1-Z

Overview

The MPQ3367GR-AEC1-Z is a six-channel boost WLED driver IC designed for automotive applications, certified to AEC-Q100 standards. It supports a maximum output current of 150 mA per channel and operates within an input voltage range of 3.5 V to 36 V. The device features a programmable switching frequency from 400 kHz to 2.2 MHz and delivers up to 50 V output voltage. It provides a dimming ratio of 15000:1 and integrates I2C control interfaces alongside analog and PWM dimming capabilities.

Feature Summary

• Six independent high-current channels for driving white LED arrays in automotive backlighting systems
• Integrated I2C interface enabling digital control and configuration of driver parameters
• Supports wide-range dimming through combined analog, PWM, and I2C modulation methods
• Automotive-grade reliability with AEC-Q100 qualification for harsh operating environments

Applications

• Automotive LCD backlighting for instrument clusters and infotainment displays
• Wide-view angle display illumination requiring uniform brightness distribution
• High-brightness LED lighting modules in vehicle interior ambient lighting systems

Procurement Notes

Verify the complete part number including suffixes such as -Z or -P to ensure correct packaging and tape-and-reel specifications. Confirm AEC-Q100 certification status if automotive compliance is mandatory for your design. Check RoHS3 compliance documentation for environmental regulations. Ensure ESD handling procedures are followed during assembly due to the QFN package sensitivity.

Selection Notes

Select this component when designing automotive display backlights requiring precise multi-channel current regulation. The I2C interface allows dynamic brightness adjustment without external microcontroller GPIO overhead. Consider the 15000:1 dimming ratio for applications demanding deep black levels and smooth transitions. Verify thermal management requirements for the QFN-24 package under maximum load conditions.

Part Context

This device belongs to the MPQ3367 family of monolithic power systems, specifically engineered for automotive LED lighting. It complements other PMIC solutions by offering dedicated channel control for complex display architectures. The series emphasizes integration and reliability for mass-produced automotive electronics.

Replacement Considerations

MPQ3367AGRE-AEC1-Z offers identical electrical characteristics with potential packaging variations. MPQ3369GR-AEC1-Z provides similar functionality but with different current ratings and frequency ranges. Verify pin compatibility and software register maps before substituting these alternatives.
