MPQ3367GF-AEC1-Z

Overview

The MPQ3367GF-AEC1-Z is a six-channel boost WLED driver IC designed for automotive backlight applications. It features an integrated internal MOSFET and supports input voltages from 3.5V to 36V, with a maximum output voltage of 50V. Each channel provides up to 150mA of regulated current. The device operates at a programmable switching frequency ranging from 340kHz to 2.42MHz. It includes I2C digital interface control, PWM dimming capabilities, and comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown.

Feature Summary

• Six independent current source channels for precise LED string regulation
• Integrated high-efficiency boost converter with internal power switch
• Digital I2C interface for configuration and monitoring
• Multiple dimming modes including direct PWM, analog, and hybrid control

Applications

• Automotive LCD panel backlighting
• In-vehicle display systems
• Dashboard illumination modules

Procurement Notes

Verify the AEC-Q100 qualification status to ensure compliance with automotive reliability standards. Confirm that the specific suffix matches the required package type and tape-and-reel specifications for your manufacturing line. Cross-reference the datasheet revision date to ensure all electrical characteristics align with your design requirements before finalizing component selection.

Selection Notes

Select this component for designs requiring high channel count and precise current matching in automotive environments. Ensure the input voltage range covers the vehicle's battery operating conditions. Verify that the thermal management solution accommodates the junction temperature limits under maximum load conditions. Check compatibility with the host controller's I2C bus speed and address configuration.

Part Context

This part belongs to the MPQ3367 family of multi-channel LED drivers from Monolithic Power Systems. It is specifically qualified for automotive use under the AEC-Q100 standard. The GF-AEC1-Z suffix indicates the automotive grade variant with specific packaging and traceability requirements distinct from consumer or industrial versions.

Replacement Considerations

Direct substitutes include other MPS MPQ3367 variants with compatible pinouts and electrical specifications. Verify equivalent AEC-Q100 certification and channel current ratings when considering alternative sources. Ensure the replacement part supports the same boost topology and I2C communication protocol.
