MP6508AGQ-Z

Overview

The MP6508AGQ-Z is a bipolar stepper motor driver manufactured by Monolithic Power Systems. It integrates four half-bridge drivers with N-channel power MOSFETs, supporting an input voltage range of 2.7V to 18V and delivering up to 1.2A output current per channel. The device operates within a temperature range of -40°C to +85°C and features a low quiescent supply current of 1.6mA. It utilizes a 16-pin QFN package (4x4mm) for surface mount installation.

Feature Summary

• Integrates four half-bridge drivers with N-channel power MOSFETs
• Supports PWM control interface for bipolar stepper motors
• Includes internal charge pump for high-side gate drive
• Features over-temperature shutdown and undervoltage lockout protection

Applications

• Bipolar stepper motor control systems
• General motion control applications
• Battery-powered devices requiring low static current

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when ordering. Confirm the QFN-16 package dimensions match the design footprint. Ensure the input voltage does not exceed 18V to prevent damage. Check datasheet for thermal dissipation requirements under load conditions.

Selection Notes

Select this component for applications requiring integrated power stages without external MOSFETs. Suitable for designs needing a wide input voltage range from 2.7V to 18V. Consider the 1.2A current capability for moderate load stepper motors. Verify compatibility with PWM control signals from the microcontroller.
