Overview
The MP7230GLE-P is a synchronous infrared LED driver IC from Monolithic Power Systems, designed for automotive applications. It supports Buck and Boost-Boost topologies with an input voltage range of 6 V to 42 V. The device delivers up to 1.2 A in boost mode or 3 A in buck mode, operating at a fixed frequency of 410 kHz. Packaged in a QFN-19 (3x4 mm) format, it features PWM dimming control and operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Integrated synchronous rectification for high efficiency in buck and boost configurations
- Supports pulse-width modulation (PWM) dimming for precise current control
- Designed specifically for infrared LED driving in driver monitoring systems
Applications
- Driver Monitoring Systems (DMS)
- Infrared LED illumination
- Automotive interior lighting
Procurement Notes
Verify the specific suffix 'P' indicates standard packaging and confirm the maximum junction temperature rating of +125°C against the latest official datasheet. Ensure compatibility with the target PCB footprint for the QFN-19 package. Cross-reference the part number with manufacturer documentation to confirm RoHS compliance status and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring a single-channel infrared LED driver with integrated power switches. It is suitable for systems needing operation across a wide automotive input voltage range. Consider the fixed 410 kHz switching frequency for inductor selection. Verify that the thermal performance of the QFN-19 package meets the system's heat dissipation requirements under maximum load conditions.
Part Context
This part belongs to the MP7230 series of LED drivers from Monolithic Power Systems. It is the non-automotive qualified version of the MPQ7230, which holds AEC-Q100 certification. Both share identical electrical specifications but differ in qualification standards. The MP7230 serves as a cost-effective alternative for non-safety-critical applications requiring similar performance characteristics.
Replacement Considerations
The MPQ7230GLE-AEC1-Z is a parameter-equivalent automotive-grade replacement. Verify that the application does not strictly require AEC-Q100 qualification before substituting the non-qualified MP7230GLE-P with the MPQ variant.
