Overview
The MPQ7200AGLE-AEC1-Z is a synchronous LED driver IC from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It supports Buck and Buck-Boost topologies within an input voltage range of 6 V to 42 V. The device delivers up to 3 A in Buck mode or 1.2 A in Buck-Boost mode. Operating at a fixed frequency of 410 kHz, it features PWM dimming capabilities. Packaged in a 19-QFN (3x4) format, it operates across a junction temperature range of -40°C to +150°C.
Feature Summary
- Supports both Buck and Buck-Boost topologies for flexible LED drive configurations
- Includes PWM dimming functionality for precise light control
- Features overcurrent protection with latch-off mode for enhanced safety
Applications
- Automotive turn indicator lights
- General automotive LED lighting systems
Procurement Notes
Verify the specific suffix 'AEC1-Z' confirms AEC-Q100 automotive qualification and RoHS compliance. Ensure the QFN-19 package matches PCB footprint requirements. Confirm that the 410 kHz switching frequency aligns with EMI constraints. Check datasheet for thermal derating curves relative to ambient conditions.
Selection Notes
Select this component when designing automotive LED circuits requiring high input voltage tolerance up to 42 V. Choose the Buck-Boost mode if input voltage may drop below LED forward voltage. Optimize external inductor selection based on the 1.2 A Buck-Boost current limit. Consider thermal management due to the wide operating temperature range.
Part Context
This part belongs to the MPQ7200 series of synchronous LED drivers. It shares the core topology with MP7200GLE-P but differs in automotive qualification and specific feature sets like thermal derating via NTC. The MPQ7200AGLE-AEC1-Z is distinct from multi-channel boost drivers like the MPQ7220GF.
Replacement Considerations
MP7200GLE-P is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 certification. Verify functional compatibility regarding pinout and control signals before substitution.
