Overview
The MP6600LGR-P is a bipolar stepper motor driver from Monolithic Power Systems, housed in a 24-QFN (4x4) package. It operates on a supply voltage range of 4.5V to 35V and delivers an output current of 1.5A. The device supports step resolutions of 1, 1/2, 1/4, and 1/8 steps. It features internal current sensing and a built-in translator, eliminating the need for external sense resistors. The operating temperature range spans from -40°C to +125°C TJ.
Feature Summary
- Integrates a built-in translator for simplified control interface
- Features internal current sensing without external components
- Provides latch-off protection for enhanced system reliability
Applications
- Printer mechanisms
- Automotive interior actuators
- Industrial motion control systems
Procurement Notes
Verify the specific suffix AEC1 or standard GR against the design requirement. Confirm the QFN-24 exposed pad thermal requirements match the PCB layout. Ensure the input voltage does not exceed the 35V maximum rating during transient conditions. Check RoHS compliance status if required by the assembly process.
Selection Notes
Select this component when a fully integrated stepper solution with internal translation is needed. It is suitable for applications requiring 1.5A drive current and multiple microstepping resolutions. Consider the 24-QFN package for space-constrained designs. Verify that the load voltage matches the 35V limit.
Part Context
This part belongs to the MP6600 family of stepper motor drivers. It shares the core architecture with variants like MP6600GR-P but includes specific enhancements such as internal current sensing and latch-off protection. The LGR suffix typically denotes the specific packaging and feature set for this automotive-grade or industrial variant.
Replacement Considerations
MP6600GR-P is a parameter-equivalent alternative within the same family. Verify if the absence of latch-off or differences in internal sensing configuration affect the specific application requirements before substitution.
