MP6501AGF-Z

Overview

The MP6501AGF-Z is a stepper motor driver from Monolithic Power Systems designed for bipolar stepper motors. It operates within an input voltage range of 8V to 35V and delivers up to 2.5A output current. The device integrates MOSFETs with a low on-resistance of 220mΩ and supports full, half, quarter, and eighth-step modes. It features a fixed 3.3V reference output, eliminating the need for separate control power supplies. Operating temperatures span from -40°C to +125°C in a TSSOP-28 package.

Feature Summary

• Integrated full bridge driver with internal MOSFETs
• Fixed 3.3V reference output for standalone operation
• Multiple micro-stepping resolution support
• Built-in thermal shutdown and overcurrent protection

Applications

• Bipolar stepper motor control systems
• Industrial automation equipment
• Motion control applications requiring compact drivers

Procurement Notes

Verify the specific suffix Z indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure thermal management design accounts for the specified power dissipation limits in the target application environment.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required without external gate drivers. The integrated MOSFETs simplify board layout compared to discrete solutions. Verify that the 8V minimum supply voltage aligns with system power rails.

Part Context

This part belongs to the MP6501A series of stepper motor controllers. It is categorized under Motor / Motion / Ignition Controllers & Drivers within the PMIC product line. The device is manufactured by Monolithic Power Systems (MPS) and utilizes surface mount technology for automated assembly.
