MPQ3326BGRE-AEC1-P

Overview

The MPQ3326BGRE-AEC1-P is a 16-channel LED lighting driver IC from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 4 V to 16 V and delivers up to 50 mA per channel in a QFN-24 package. The device supports PWM dimming at a frequency of 245 Hz and includes integrated short circuit and thermal protection mechanisms.

Feature Summary

• Supports separated PWM and analog dimming control via I2C interface
• Includes built-in short circuit and thermal protection features
• Qualified for automotive environments under AEC-Q100 standards

Applications

• Automotive interior LED lighting systems
• Ambient mood lighting circuits
• Dashboard illumination drivers

Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive grade qualification and pin compatibility. Confirm the 'P' suffix indicates reel packaging if required by assembly equipment. Ensure the design accounts for the 245 Hz PWM frequency limitation during system integration.

Selection Notes

Select this component when a high-channel-count solution is required for automotive LED arrays. It is suitable for designs needing independent channel control via I2C. Consider the 50 mA output limit per channel against total load requirements. The QFN-24 package offers a compact footprint for space-constrained PCB layouts.

Part Context

This part belongs to the MPQ3326 family of multi-channel LED drivers. It shares functional similarities with the MPQ3326GR variant but differs in specific automotive qualification or packaging details. The series is targeted at complex lighting architectures requiring precise current regulation across multiple outputs.

Replacement Considerations

MPQ3326GR-AEC1-P is a related variant within the same family. Verify channel count, current limits, and package dimensions before substitution to ensure electrical and mechanical compatibility.
