Overview
The MPC17531AEV is a dual H-bridge motor driver IC manufactured by NXP USA Inc. It integrates internal control logic, a charge pump, gate drive circuitry, and high-current low RDS(on) MOSFET output stages. The device supports driving a single two-phase stepper motor or two brushed DC motors. It operates with a supply voltage range of 2.7V to 3.6V and handles load voltages from 2V to 8.6V. The output current capability is specified at 700mA per channel. The component utilizes a parallel interface and is housed in a 20-VMFP package.
Feature Summary
- Integrates full control and power stages including internal logic and charge pump
- Capable of driving either a single two-phase stepper motor or two brushed DC motors
- Features high-current, low on-resistance MOSFET output circuitry
Applications
- Battery-powered applications
- Stepper motor control systems
- Brushed DC motor drives
Procurement Notes
Verify the specific suffix for the requested variant, as the MPC17531A family includes multiple packages such as HVQFN24 and HTSSOP20. Confirm availability status, as some variants are marked as End of Life or discontinued. Ensure the selected part number matches the required package type and environmental certifications like RoHS compliance before ordering.
Selection Notes
Select this component when a fully integrated dual H-bridge solution is required for low-voltage battery-operated devices. The 2.7V to 3.6V supply range makes it suitable for single-cell lithium-ion applications. Consider the 20-VMFP package for surface-mount assembly constraints. Verify thermal performance requirements given the 150°C junction temperature rating.
Part Context
The MPC17531A belongs to NXP's motor driver portfolio designed for compact motion control applications. It consolidates gate drivers, charge pumps, and power MOSFETs into a single chip to reduce external component count. This integration simplifies PCB layout and improves reliability compared to discrete H-bridge implementations.
Replacement Considerations
Check for alternative dual H-bridge drivers from NXP or other manufacturers that support similar voltage ranges and current ratings. Verify pin compatibility if replacing in an existing design. Note that some MPC17531 variants are discontinued, so long-term supply agreements should be confirmed.
