Overview
The MPC17531ATEP is a dual H-bridge integrated circuit manufactured by NXP Semiconductors, formerly Freescale. It incorporates internal control logic, a charge pump, gate drivers, and high-current low RDS(on) MOSFET output circuitry. The device is designed to drive either a single two-phase stepper motor or two brushed DC motors simultaneously.
Feature Summary
- Integrates internal control logic and charge pump for simplified system design
- Features high-current, low on-resistance MOSFET output stages
- Capable of driving a single two-phase stepper motor or two independent brushed DC motors
Applications
- Driving single two-phase stepper motors
- Driving two separate brushed DC motors
- Evaluation board integration for motor control development
Procurement Notes
Verify the manufacturer designation as NXP Semiconductors, noting that Freescale was acquired in December 2015. Confirm the specific suffix ATEP against official datasheets to ensure correct package and temperature grade specifications. Cross-reference with current NXP product documentation rather than legacy Freescale materials.
Selection Notes
Select this component when a dual-channel motor driver solution is required for stepper or brushed DC applications. The integrated charge pump and control logic reduce external component count compared to discrete solutions. Ensure the application requires the specific current handling and voltage ratings supported by the dual H-bridge architecture.
Part Context
This part belongs to the MPC17531A family of dual H-bridge motor drivers. The Freescale brand was retired following its merger into NXP Semiconductors. Official documentation and support are now managed exclusively under the NXP portfolio, requiring updated reference materials for technical validation.
Replacement Considerations
Consult NXP official documentation for verified substitute part numbers within the MPC17531A series. Do not assume functional equivalence with other motor driver families without explicit cross-reference data from the manufacturer.
