MPQ3369GF-AEC1-Z

Overview

The MPQ3369GF-AEC1-Z is a six-channel WLED driver IC designed for automotive applications, certified to AEC-Q100 standards. It supports Boost and SEPIC topologies with an input voltage range of 3.5 V to 36 V. Each channel delivers up to 100 mA output current at a fixed switching frequency of 2.2 MHz. The device features a 15000:1 dimming ratio via PWM control and I2C interface. It is housed in a TSSOP-EP-28 package and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Supports independent control of six LED channels with high brightness uniformity
• Enables precise dimming through a wide 15000:1 ratio using PWM signals
• Integrates I2C interface for configuration and status monitoring
• Provides robust protection mechanisms including open/short circuit detection

Applications

• Automotive exterior lighting systems
• Interior ambient illumination modules
• Dashboard and instrument cluster backlighting
• High-brightness indicator arrays

Procurement Notes

Verify the specific suffix GF-AEC1-Z to confirm the TSSOP-EP-28 package and automotive qualification. Ensure compatibility with the required PCB footprint and thermal management strategy. Confirm that the design supports the specified 2.2 MHz switching frequency and I2C bus requirements. Check for any regional distribution restrictions or lead time variations associated with this specific part number variant.

Selection Notes

Select this component when a six-channel solution with high dimming precision is required for automotive environments. The TSSOP-EP-28 package offers a balance between pin count and board space compared to QFN alternatives. Consider the 100 mA per channel limit for LED string sizing. The integrated I2C interface simplifies system control logic compared to purely analog-driven counterparts.

Part Context

This part belongs to the MPQ3369 family of multi-channel LED drivers from Monolithic Power Systems. It shares core electrical specifications with variants like MPQ3369GR-AEC1-Z but differs in packaging. The GF suffix specifically denotes the TSSOP-EP-28 form factor, distinguishing it from the QFN-24 option found in other family members.

Replacement Considerations

MPQ3369GR-AEC1-Z is a functional equivalent within the same family but utilizes a QFN-24 package instead of TSSOP-EP-28. Verify PCB layout compatibility before substitution as the pinout and thermal pad configurations differ significantly between these two packages.
