MPQ7220GR-AEC1-Z

Overview

The MPQ7220GR-AEC1-Z is a six-channel boost LED driver IC designed for automotive applications, qualified to AEC-Q100 standards. It operates within an input voltage range of 3.5 V to 36 V and delivers a maximum output current of 100 mA per channel. The device supports PWM dimming control and features an adjustable switching frequency up to 2.2 MHz. Packaged in a 24-QFN (4x4) surface-mount format, it ensures reliable performance across a temperature range of -40°C to +125°C.

Feature Summary

• Six independent constant-current channels for multi-zone LED driving
• Integrated high-voltage boost converter topology
• Automotive-grade reliability with AEC-Q100 qualification
• Supports precise pulse-width modulation dimming

Applications

• Automotive interior ambient lighting systems
• Instrument cluster backlighting arrays
• Dashboard illumination modules
• Door handle and logo lighting circuits

Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive grade compliance and RoHS status. Confirm the QFN-24 package dimensions match PCB layout requirements. Ensure the design accounts for thermal dissipation limits specified in the datasheet. Validate that the 36V input rating aligns with vehicle electrical system specifications.

Selection Notes

Select this component when designing multi-channel automotive lighting requiring a single boost regulator solution. It is suitable for applications needing synchronized PWM dimming across multiple zones. Consider the 100mA per channel limit for LED string configurations. Evaluate the 2.2MHz frequency for EMI management and passive component sizing.

Part Context

This part belongs to the MPQ7220 family of LED drivers from Monolithic Power Systems. It is specifically engineered for automotive environments, distinguishing it from industrial variants through its extended temperature range and robust qualification. The six-channel architecture allows for complex lighting patterns without requiring multiple discrete controllers.

Replacement Considerations

MPQ7220GR is listed as a related part number. Verify if the non-AEC1 variant meets the required automotive qualification and temperature specifications before substitution.
