Overview
The MP6500GF-P is a bipolar stepper motor driver from Monolithic Power Systems, featuring an integrated translator and current regulator. It operates on a supply voltage range of 4.5 V to 35 V with a maximum output current of 2.5 A. The device supports full, half, quarter, and eighth-step modes. Key electrical parameters include a quiescent supply current of 1.9 mA and a power dissipation capability defined by its thermal design. It utilizes a TSSOP-EP-28 package for surface mount installation.
Feature Summary
- Integrates internal current sampling and regulation, eliminating the need for external sense resistors.
- Includes a built-in step/direction translator supporting multiple microstepping resolutions.
- Features comprehensive protection mechanisms including overcurrent, overvoltage, undervoltage lockout, and overtemperature shutdown.
Applications
- Printer mechanisms
- Office automation equipment
- Industrial control systems
Procurement Notes
Verify the specific suffix 'GF' corresponds to the TSSOP-28 EP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinouts with the latest datasheet revision to avoid compatibility issues during PCB layout.
Selection Notes
Select this component for applications requiring high integration in bipolar stepper motor drives. The internal translator simplifies interface requirements compared to discrete driver solutions. Consider the TSSOP-28 EP package for improved thermal performance relative to smaller footprints. Evaluate the 2.5 A current limit against specific motor load requirements to ensure adequate headroom.
Part Context
This part belongs to the MP6500A series of integrated stepper motor drivers. It shares functional similarities with other MPS motor control ICs but is distinguished by its specific package configuration and parameter set. The series targets cost-sensitive, space-constrained designs requiring reliable motion control without complex external circuitry.
Replacement Considerations
MP6500GU-P offers identical functionality in a QFN-24 package. MP6500GF-Z is the same device in a tape-and-reel packaging format. Verify package dimensions and thermal pad requirements when substituting between GF and GU variants.
