MPQ7235GQBE-AEC1-P

Overview

The MPQ7235GQBE-AEC1-P is an automotive-grade infrared LED driver IC manufactured by Monolithic Power Systems. It features a synchronous buck topology with a maximum input voltage of 36 V and a minimum of 4 V. The device delivers up to 3 A output current at a fixed switching frequency of 2.2 MHz. It is qualified to AEC-Q100 standards for automotive applications, operating within a temperature range of -40°C to +125°C. The component is housed in a QFN-13 package.

Feature Summary

• Integrated synchronous buck converter architecture optimized for high-efficiency IR LED driving
• AEC-Q100 qualification ensuring reliability for demanding automotive environments
• Supports dimming functionality for precise control of infrared illumination intensity

Applications

• Automotive infrared lighting systems
• Night vision camera illumination drivers
• ADAS sensor auxiliary lighting

Procurement Notes

Verify the specific suffix 'AEC1' confirms AEC-Q100 automotive qualification status. Ensure the 'P' suffix matches the required tape and reel packaging configuration for automated assembly processes. Cross-reference the QFN-13 footprint dimensions against the target PCB layout to guarantee mechanical compatibility during procurement validation.

Selection Notes

Select this component when designing circuits requiring a single-channel, high-current solution for infrared LEDs. The 36 V input limit accommodates standard automotive battery voltages. Consider the 2.2 MHz frequency for balancing EMI performance against passive component size requirements compared to lower-frequency alternatives.

Part Context

This part belongs to the MPQ series of power management integrated circuits from Monolithic Power Systems. It is specifically engineered for automotive applications, distinguishing it from general-purpose industrial variants through its extended temperature rating and rigorous qualification standards required for vehicle integration.

Replacement Considerations

The MP7235GQBE-Z is listed as a related product variant. Verify if the non-AEC1 suffix meets the specific automotive qualification requirements of the target application before substitution.
