Overview
The MPQ3369GR-Z is a six-channel WLED driver IC from Monolithic Power Systems, designed for automotive and industrial lighting applications. 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 PWM dimming with a 15000:1 ratio and I2C interface control. It operates within a temperature range of -40°C to +125°C and is housed in a 24-QFN (4x4 mm) package.
Feature Summary
- Supports Boost and SEPIC topologies for flexible LED string configurations
- Provides high-precision PWM dimming with a 15000:1 ratio
- Integrates I2C interface for digital control and configuration
- Includes internal power switches for compact system design
Applications
- Automotive exterior lighting systems
- Interior ambient LED illumination
- Industrial backlighting arrays
- High-density LED matrix drivers
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the package type matches the 24-QFN footprint requirements for your PCB layout. Ensure the I2C address configuration aligns with your system's bus architecture. Check for any specific automotive qualification requirements if deploying in AEC-Q100 environments.
Selection Notes
Select this component when multiple independent LED channels require precise current regulation and high-dynamic-range dimming. The integrated I2C interface simplifies control logic compared to analog alternatives. Consider the 2.2 MHz switching frequency for balancing EMI performance and external component size. Verify that the 36 V maximum input voltage covers your system's transient conditions.
Part Context
This part belongs to the MPQ3369 family of multi-channel LED drivers. It shares functional similarities with the MPQ3369GF-AEC1-Z but differs in package and automotive qualification. The GR-Z variant utilizes a QFN package suitable for surface-mount assembly. It complements single-channel drivers like the MP3363GJ-Z by offering higher integration for complex lighting arrays.
Replacement Considerations
MPQ3369GF-AEC1-Z offers similar functionality with TSSOP-EP-28 packaging and AEC-Q100 qualification. MPQ3369GR-AEC1-P provides equivalent electrical performance with different suffix variations. Verify pinout compatibility and thermal dissipation characteristics before substituting.
