Overview
The MP6507GF-Z is a bipolar stepper motor driver from Monolithic Power Systems, designed for applications requiring efficient control within a 2.7V to 15V supply range. It integrates two full-bridge drivers with N-channel power MOSFETs, delivering up to 700mA output current per channel. The device features a low static current of 1.1mA and includes internal safety mechanisms such as over-temperature shutdown, under-voltage lockout, and current limiting via external sensors. Packaged in a 16-pin TSSOP-EP with an exposed thermal pad, it supports operation across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates dual full-bridge drivers with low on-resistance N-channel power MOSFETs
- Includes internal charge pump for high-side gate drive
- Provides comprehensive protection against over-temperature and under-voltage conditions
Applications
- Battery-powered devices
- Small appliance motor control
- Precision motion control systems
Procurement Notes
Verify the specific suffix (e.g., GF-Z vs GQ-Z) to confirm the package type, as the base part number covers multiple physical footprints. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the design accounts for the thermal performance of the TSSOP-EP package given the exposed pad requirement.
Selection Notes
Select this component when a compact solution for low-current bipolar stepper motors is required. The TSSOP-EP package offers better thermal dissipation compared to standard QFN options for similar power levels. Consider the 1µA sleep mode current if battery life is a critical constraint for the end application.
Part Context
The MP6507 belongs to a family of integrated stepper motor drivers that combine control logic and power stages. It serves as a cost-effective alternative to discrete solutions, simplifying PCB layout by integrating the bridge drivers and charge pump. The GF variant specifically utilizes the TSSOP-EP package, distinguishing it from other pin-compatible or functionally similar parts in the series.
Replacement Considerations
Direct substitutes include MP6507GQ-Z (QFN-16 package) and MP6507GR-Z (QFN-16 package). Verify thermal requirements and footprint compatibility before swapping packages, as the TSSOP-EP differs physically from the QFN variants despite identical electrical specifications.
