Overview
The MP6507GQ-P is a bipolar stepper motor driver from Monolithic Power Systems. It integrates dual full-bridge N-channel power MOSFETs and operates within an input voltage range of 2.7 V to 15 V. The device delivers up to 700 mA output current per channel. Key electrical parameters include a maximum on-resistance of 500 mΩ for both high-side and low-side MOSFETs, a typical operating supply current of 1.1 mA, and a sleep mode current of 1 µA. It features internal charge pump drive, over-temperature shutdown with flag output, and under-voltage lockout protection.
Feature Summary
- Integrates dual full-bridge drivers with built-in N-channel power MOSFETs
- Includes internal charge pump for high-side gate drive
- Provides thermal protection with over-temperature shutdown and status flag
- Supports external current sensing via sensor resistors
Applications
- Bipolar stepper motor control systems
- Small appliance motor drives
- Industrial automation positioning modules
- Office equipment motion control
Procurement Notes
Verify the specific suffix GQ-P against official MPS documentation to confirm the QFN-16 package variant and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet before procurement. Ensure the ordering part number matches the required pin configuration and thermal pad specifications for your PCB layout.
Selection Notes
Select this component when driving bipolar stepper motors requiring up to 700 mA per phase. The integrated MOSFETs eliminate the need for external discrete switches. Consider the 500 mΩ on-resistance for thermal management in compact designs. The low sleep current makes it suitable for battery-powered applications requiring power conservation.
Part Context
This part belongs to the MP6507 series of stepper motor drivers manufactured by Monolithic Power Systems. It is designed as a complete solution for bipolar stepper motor applications, combining logic control and power stages in a single IC. The series offers various package options including TSSOP and QFN variants to suit different thermal and space constraints.
Replacement Considerations
MP6507GQ-Z is a verified alternative within the same product family offering identical functionality but potentially differing in lead-free or halogen-free certification status.
