MP6507GF-P

Overview

The MP6507GF-P is a bipolar stepper motor driver from Monolithic Power Systems, designed for applications requiring precise motion control. It integrates two full-bridge N-channel power MOSFETs capable of delivering up to 700mA output current per channel. The device operates within a supply voltage range of 2.7V to 15V and features a TSSOP-EP-16 package with an exposed pad for enhanced thermal performance. Key electrical parameters include a maximum power dissipation of 2.8W and a quiescent current of 1.1mA. It supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates dual full-bridge drivers with low on-resistance N-channel MOSFETs
• Includes internal charge pump for high-side gate drive
• Provides comprehensive protection against over-temperature and under-voltage lockout
• Features an over-temperature status flag for system monitoring

Applications

• Bipolar stepper motor control in industrial automation
• Motion control systems in office equipment
• Precision positioning mechanisms in medical devices

Procurement Notes

Verify the specific suffix GF-P corresponds to the TSSOP-EP-16 package variant when ordering. Confirm that external current sensing components are included in the design, as the MP6507GF-P utilizes external sensors for current limiting functions. Ensure thermal management strategies account for the 2.8W power dissipation rating in the final application layout.

Selection Notes

Select the MP6507GF-P for designs requiring a compact solution for bipolar stepper motors with moderate current demands up to 700mA. Consider the TSSOP-EP-16 package for improved heat dissipation compared to standard packages. Evaluate the need for external current sense resistors to configure the peak current limit according to the specific motor requirements.

Part Context

The MP6507 series represents MPS's entry-level bipolar stepper motor drivers, focusing on cost-effective and space-efficient solutions. The MP6507GF-P specifically denotes the version housed in a 16-pin TSSOP package with an exposed thermal pad, distinguishing it from QFN variants like the MP6507GR-P or other pin-out configurations within the same family.

Replacement Considerations

Direct substitutes within the MP6507 family include MP6507GF-Z (same package, different suffix) and MP6507GQ-P (QFN package). Cross-package replacements such as MP6507GR-P require PCB footprint adaptation. Verify voltage and current ratings match if considering higher-end drivers like the MP6508.
