MPQ3367GRE-AEC1-P

Overview

The MPQ3367GRE-AEC1-P is a six-channel boost WLED driver IC designed for automotive applications, certified to AEC-Q100 standards. It supports an input voltage range of 3.5 V to 36 V and delivers up to 150 mA per channel with a maximum output voltage of 50 V. The device operates at switching frequencies between 400 kHz and 2.2 MHz. It features I2C control and supports analog, PWM, and hybrid dimming methods with a ratio up to 15000:1. Packaged in a 24-pin QFN-WF (4x4 mm) with wettable flanks, it functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Six independent current-regulated channels for driving white LED arrays
• I2C interface for digital configuration and control
• Supports analog, PWM, and hybrid dimming techniques
• Automotive-grade reliability with AEC-Q100 certification

Applications

• Automotive LCD panel backlighting
• Virtual reality display backlighting
• Tablet and notebook screen illumination

Procurement Notes

Verify the specific suffix 'GRE' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the design accounts for the 24-VFQFN wettable flank requirements for inspection. Confirm that the application environment meets the specified operating temperature range and input voltage constraints before finalizing procurement.

Selection Notes

Select this component when designing systems requiring high-precision current regulation for multiple LED strings in automotive environments. The integrated I2C interface allows for dynamic brightness adjustment and fault monitoring. Consider the 150 mA per channel limit and the 50 V maximum output voltage when sizing the external inductor and capacitors for the boost topology.

Part Context

This part belongs to the MPQ3367 family of LED drivers from Monolithic Power Systems. Variants such as MPQ3367AGR and MPQ3367GR share similar electrical characteristics but may differ in packaging or reel specifications. The GRE suffix typically denotes a specific tape and reel configuration for automated assembly.

Replacement Considerations

Direct substitutes include MPQ3367AGR-AEC1-P and MPQ3367GR-AEC1-P. Verify pinout compatibility and thermal performance differences due to potential packaging variations before substitution.
