MPQ7228GQJE-0000-AEC1-Z

Overview

The MPQ7228GQJE-0000-AEC1-Z is a 16-channel current sink LED driver IC from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It features pre-programmed animations and supports PWM dimming. The device operates within an input voltage range of 3.1 V to 3.5 V and delivers up to 200 mA per channel. It utilizes a buck topology and is housed in a QFN-32 package. The component functions at switching frequencies between 250 Hz and 1 kHz, with a maximum power dissipation of 5.9 W and an operating temperature range from -40°C to +150°C.

Feature Summary

• Integrates sixteen independent constant-current sink channels for precise LED control.
• Includes built-in pre-programmed animation sequences for dynamic lighting effects.
• Optimized thermal performance with cooler thermals and efficiency improvements.
• Supports pulse-width modulation (PWM) dimming for brightness adjustment.

Applications

• Automotive exterior lighting systems
• Interior ambient illumination modules
• Dashboard indicator arrays
• Adaptive front-lighting systems

Procurement Notes

Verify the specific suffix AEC1-Z against official Monolithic Power Systems documentation to confirm automotive grade compliance and pinout configuration. Ensure that the required input voltage range aligns with the system's power supply architecture before procurement. Cross-reference the QFN-32 package dimensions with PCB layout guidelines to guarantee proper thermal and mechanical integration. Confirm availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when designing automotive lighting circuits requiring multiple synchronized channels with integrated animation capabilities. It is suitable for applications where low input voltage operation is necessary and high channel count is preferred over higher individual current output. Consider the thermal management requirements due to the 5.9 W power dissipation rating. Evaluate the compatibility of the PWM dimming interface with the host controller's signaling capabilities.
