MP6508GR-P

Overview

The MP6508GR-P is a stepper motor driver manufactured by Monolithic Power Systems. It operates on a supply voltage range of 2.7 V to 18 V and delivers an output current of 1.2 A. The device features a full bridge topology with integrated MOSFETs. It functions within a temperature range of -40 °C to +85 °C and consumes 1.6 mA in operating mode. The unit dissipates up to 2.7 W of power and is housed in a QFN-16 package for surface mount installation.

Feature Summary

• Integrates a full bridge driver with internal power MOSFETs for bipolar stepper motors
• Supports PWM control interface for precise motor operation
• Includes thermal shutdown protection to safeguard against overheating

Applications

• Bipolar stepper motor control systems
• Motion control applications requiring integrated drive solutions
• Automotive ignition or actuator drivers

Procurement Notes

Verify the specific suffix GR-P to confirm the QFN-16 package type, as other suffixes may indicate different packages like TSSOP. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for low-voltage bipolar stepper motors is required. Ensure the application voltage remains within the 2.7 V to 18 V limit and that the thermal design accommodates the specified power dissipation capabilities of the QFN-16 package.

Part Context

This part belongs to the MP6508 series from Monolithic Power Systems. It serves as a specialized driver for motion control tasks, distinct from brushless DC pre-drivers or LED controllers found in the same manufacturer's portfolio. The GR-P designation specifically identifies the QFN-16 variant.

Replacement Considerations

MP6508GR-Z is a direct substitute offering identical electrical performance but utilizes a TSSOP-16 package instead of QFN-16.
