Overview
The MP6500AGF-Z is a bipolar stepper motor driver from Monolithic Power Systems, featuring integrated MOSFETs and internal current sensing. It operates within an input voltage range of 4.5V to 35V and delivers up to 2.5A output current. The device supports full, half, quarter, and eighth-step modes. Key electrical parameters include a maximum power dissipation of 3.5W and a supply current of 1.5mA. It functions across a temperature range of -40°C to +125°C and utilizes a TSSOP-EP-28 package.
Feature Summary
- Integrates two internal full-bridge drivers with built-in current regulation, eliminating the need for external sense resistors.
- Provides comprehensive protection mechanisms including over-current protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown.
- Features a simple logic interface compatible with both 3.3V and 5V logic levels without requiring separate control power supplies.
Applications
- Printer mechanisms
- Office automation equipment
- Security systems
Procurement Notes
Verify the specific suffix AGF-Z against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with the target PCB footprint, specifically the TSSOP-EP-28 package with exposed pad. Confirm moisture sensitivity level requirements for assembly processes. Cross-reference the part number with official MPS documentation to validate RoHS compliance status.
Selection Notes
Select this component when designing compact bipolar stepper motor drives requiring high integration. It is suitable for applications needing precise current control without external sensing components. Consider the thermal performance of the TSSOP-EP-28 package for heat dissipation needs. Evaluate the 2.5A current capability against the specific motor requirements to ensure adequate headroom.
Part Context
This part belongs to the MP6500 series of integrated bipolar stepper motor drivers. The series is designed to offer space-saving solutions with high efficiency. Other variants in the family include different package options like QFN-24. The MP6500AGF-Z specifically denotes the TSSOP-EP-28 package variant with lead-free finishing.
Replacement Considerations
MP6500GF-Z is a verified substitute offering identical functionality in a TSSOP-28 EP package. MP6500GU-P provides the same electrical specifications in a QFN-24 package, requiring layout adaptation.
