MPQ3387LGRT-AEC1-P

Overview

The MPQ3387LGRT-AEC1-P is an automotive-grade white LED driver IC from Monolithic Power Systems. It utilizes a boost topology to drive up to six LED strings with a maximum current of 45 mA per string. The device operates within a supply voltage range of 3 V to 25 V and features a fixed switching frequency of 1.25 MHz. It supports PWM dimming for brightness control and is housed in a TQFN-24 package. The component is qualified under AEC-Q100 standards, ensuring reliability for temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Supports six independent output channels for driving multiple white LED strings
• Integrates a step-up boost converter topology for efficient power management
• Enables precise brightness regulation through pulse-width modulation (PWM) dimming

Applications

• Automotive exterior lighting systems
• Vehicle interior illumination modules
• Dashboard and ambient lighting circuits

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact reel quantity and tape-and-reel specifications. Ensure that the procurement channel provides valid traceability documentation required for automotive-grade components. Cross-reference the manufacturer's datasheet to confirm the latest revision status before finalizing orders.

Selection Notes

Select this component when designing systems requiring high reliability in harsh thermal environments. The wide input voltage range accommodates various vehicle power architectures. Consider the TQFN-24 package size for PCB layout constraints. Verify that the application requires PWM dimming capabilities and can support the specified switching frequency.

Part Context

This part belongs to the MPQ3387 series of LED drivers designed specifically for automotive applications. It shares functional similarities with other members of the family but is distinguished by its specific packaging and qualification level. The series focuses on providing robust solutions for multi-string LED configurations in transportation sectors.

Replacement Considerations

The MPQ3387LGRT-Z serves as the industrial-grade equivalent within the same product family. Engineers should verify if the industrial temperature rating meets the system requirements if the automotive qualification is not strictly necessary.
