MP6501AGF

Overview

The MP6501AGF is a stepper motor driver from Monolithic Power Systems designed for bipolar stepper motors. It operates on an input voltage range of 8V to 35V and delivers up to 2.5A output current. The device features integrated MOSFETs with low on-resistance and includes internal safety mechanisms such as overcurrent protection, input overvoltage protection, undervoltage lockout, and thermal shutdown. It supports full-step, half-step, quarter-step, and eighth-step modes. A fixed 3.3V reference output eliminates the need for separate control power supplies. The component is housed in a TSSOP-EP-28 package suitable for surface mount applications.

Feature Summary

• Integrated micro-stepping converter supporting multiple resolution modes including full, half, quarter, and eighth steps
• Built-in comprehensive protection circuitry covering overcurrent, overvoltage, undervoltage lockout, and thermal conditions
• Fixed 3.3V reference output enabling direct microcontroller interfacing without auxiliary control power

Applications

• Bipolar stepper motor control systems
• Motion control applications requiring precise positioning
• Automation equipment utilizing micro-stepping capabilities

Procurement Notes

Verify the specific suffix (P or Z) against your supply chain requirements, as packaging formats differ between reel and cut tape options. Confirm moisture sensitivity handling procedures are followed during storage and assembly. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the exact part number with official manufacturer documentation to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when driving bipolar stepper motors within the specified voltage and current limits. The integrated micro-stepping functionality reduces mechanical resonance and improves smoothness compared to basic drivers. Consider the TSSOP-EP-28 package for thermal management needs due to the exposed pad design. Evaluate the internal protection features if your application environment presents risks of electrical faults or thermal overload.
