MPQ7235GQBE-AEC1-Z

Overview

The MPQ7235GQBE-AEC1-Z is a synchronous buck LED driver IC from Monolithic Power Systems, designed for automotive infrared lighting applications. It features a wide input voltage range of 4 V to 36 V and delivers up to 3 A output current. The device operates at a fixed switching frequency of 2.2 MHz and supports PWM dimming control. Qualified under AEC-Q100 standards, it ensures reliability in harsh environments with an operating temperature range of -40°C to +125°C. Packaged in a compact QFN-13 format, this single-output driver integrates high-side and low-side MOSFETs for efficient power conversion.

Feature Summary

• AEC-Q100 qualified for automotive grade reliability
• Integrated synchronous buck topology for high efficiency
• Supports PWM dimming for precise brightness control
• Wide input voltage range accommodating various supply conditions

Applications

• Automotive infrared LED lighting systems
• Night vision camera illumination drivers
• ADAS sensor light sources
• Automotive interior ambient lighting with IR capability

Procurement Notes

Verify the complete part number including suffixes such as -Z for tape and reel packaging when ordering. Confirm AEC-Q100 qualification status is required for your specific automotive application tier. Check local distributor availability as stock levels may vary by region. Ensure the QFN-13 package footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring high current drive for IR LEDs within a 36V automotive system. Consider the 2.2 MHz frequency for smaller external passive components compared to lower frequency alternatives. Evaluate thermal performance in the QFN-13 package against your board's heat dissipation capabilities. Compare against non-automotive versions if cost is critical but automotive qualification is not mandatory.

Part Context

This part belongs to MPS's MPQ7235 family of synchronous buck LED drivers. It shares architectural similarities with the MP7235GQBE-Z but includes additional automotive qualification markings. The series targets high-efficiency lighting solutions where size and reliability are paramount. Other family members may offer different current ratings or input ranges.

Replacement Considerations

The MP7235GQBE-Z is a non-automotive equivalent with identical electrical specifications. Verify that the absence of AEC-Q100 certification meets your project requirements. No other direct substitutes are documented in the provided data.
