MPQ7231GLE-D10-AEC1-Z

Overview

The MPQ7231GLE-D10-AEC1-Z is a synchronous infrared LED driver from Monolithic Power Systems, qualified to AEC-Q100 Grade 1 standards. It supports buck topology with a 3A output current and buck-boost topology with a 2.4A output current. The device operates within a 6V to 42V supply voltage range and features fixed switching frequencies of 1.25MHz or 2.4MHz. It utilizes PWM dimming control and is housed in a compact 19-pin QFN (3x4mm) package designed for surface-mount assembly.

Feature Summary

Integrated synchronous power stage for high-efficiency infrared LED driving
Supports both buck and buck-boost topologies for flexible input voltage ranges
Automotive-grade reliability with AEC-Q100 Grade 1 qualification
Fixed-frequency operation at 1.25MHz or 2.4MHz for optimized component size

Applications

Automotive infrared lighting systems
Night vision camera illumination
Advanced Driver Assistance Systems (ADAS) light sources
Automotive interior ambient sensing

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm the exact switching frequency configuration, as variants exist. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Confirm that the application environment remains within the specified -40°C to +150°C junction temperature range for reliable automotive operation.

Selection Notes

Select this component when designing infrared LED drivers requiring AEC-Q100 Grade 1 certification. Choose between the 1.25MHz and 2.4MHz variants based on external inductor size constraints and electromagnetic interference requirements. Ensure the input voltage range aligns with the vehicle's power bus and that the load current does not exceed the 3A buck or 2.4A buck-boost limits.

Part Context

This device belongs to the MPQ7231 series of infrared LED drivers. It shares the same package footprint and general functionality with other members of the family but differs in switching frequency settings defined by the D10 suffix. It is distinct from the MPQ7230 series, which offers lower current capabilities and different frequency options.
