MPQ7231GLE-D00-AEC1-P

Overview

The MPQ7231GLE-D00-AEC1-P is an automotive-grade infrared LED driver IC from Monolithic Power Systems. It supports Buck and Boost topologies with a 6V to 42V input range. The device delivers up to 2.4A output current in Buck mode or 1.2A in Boost mode, operating at a fixed frequency of 410kHz. Packaged in a 19-QFN (3x4mm) format, it features PWM dimming and AEC-Q100 qualification for temperatures up to 150°C TJ.

Feature Summary

Integrated synchronous switching architecture supporting both step-down and step-up configurations for flexible LED drive requirements.
Automotive-grade reliability certified under AEC-Q100 standards for harsh environment operation.
Precision pulse-width modulation control interface enabling accurate infrared light intensity regulation.

Applications

Driver Monitoring Systems
Automotive Infrared Lighting
Advanced Driver Assistance Systems

Procurement Notes

Verify the specific D00 suffix against official datasheets to confirm pinout and functional variations within the MPQ7231 family. Ensure component authenticity through authorized distribution channels. Confirm package marking matches the 19-QFN specification. Validate thermal performance requirements against the 150°C junction temperature rating before final integration.

Selection Notes

Select this component when designing systems requiring combined buck-boost capability for infrared LEDs within automotive environments. The 410kHz frequency offers a balance between efficiency and external component size. Verify that the 2.4A peak current meets load demands during buck operation while ensuring boost mode limits align with system constraints.

Part Context

This part belongs to the MPQ7230/MPQ7231 series of synchronous LED drivers designed specifically for automotive applications. It shares architectural similarities with the MPQ7230 but offers optimized current capabilities for infrared lighting solutions. The series targets compact form factors required in modern vehicle sensor arrays.

Replacement Considerations

MPQ7231GLE-D00-Z is listed as a parameter-equivalent alternative by the manufacturer. Verify electrical compatibility and package dimensions before substitution.
