MPQ3326BGRE-AEC1-Z

Overview

The MPQ3326BGRE-AEC1-Z is a 16-channel linear LED driver IC designed for automotive applications, holding AEC-Q100 qualification. It delivers an output current of 80 mA per channel with a maximum power dissipation of 2.97 W. The device operates on a supply voltage range of 4.5 V to 16 V and supports switching frequencies of 220 Hz, 250 Hz, 280 Hz, and 330 Hz. It features separated PWM and analog dimming capabilities controlled via an I2C interface, which defaults to enabled. Packaged in a QFN-24 format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

Supports independent control of 16 channels with separated PWM and analog dimming interfaces.
Integrated I2C communication interface for configuration and control.
Automotive-grade reliability certified under the AEC-Q100 standard.

Applications

Automotive interior lighting systems
Ambient cabin illumination circuits
LED matrix backlighting modules

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific suffix matches the required automotive grade specifications. Ensure compatibility with existing PCB layouts regarding the QFN-24 package dimensions and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing high-channel-count automotive LED drivers requiring precise current regulation. The 80 mA per channel rating suits low-to-medium brightness applications. Verify that the system input voltage remains within the 4.5 V to 16 V operational window. Consider the thermal management needs associated with the 2.97 W power dissipation limit in the QFN-24 package.

Part Context

This part belongs to the Monolithic Power Systems MPQ3326B series, specifically engineered for automotive environments. It serves as a specialized solution for managing multiple LED strings in vehicle interiors. The designation indicates compliance with strict automotive quality standards, distinguishing it from general-purpose industrial counterparts.
