MPC17531ATEJR2

Overview

The MPC17531ATEJR2 is a dual H-bridge motor driver integrated circuit manufactured by NXP Semiconductors. It operates within a supply voltage range of 2V to 8.6V and supports output currents up to 1.4A. The device features an internal control logic, charge pump, gate drive, and high-current low RDS(on) MOSFET output circuitry. Designed for driving single two-phase stepper motors or two brushed DC motors, it utilizes a 20-pin HTSSOP package with a tape and reel (R2) configuration. The component is currently classified as End of Life.

Feature Summary

• Integrates internal control logic, charge pump, and gate drive for simplified system design
• Supports driving of single two-phase stepper motors or two independent brushed DC motors
• Incorporates high-current, low on-resistance MOSFET output stage for efficient power delivery

Applications

• Driving single two-phase stepper motors
• Driving two separate brushed DC motors
• Battery-powered applications requiring compact motor control

Procurement Notes

This component is officially designated as End of Life by the manufacturer. Procurement should be approached with caution due to limited availability in the secondary market. Verify authenticity through authorized channels and request Certificates of Analysis to ensure compliance with RoHS and REACH standards before integration into production systems.

Selection Notes

Engineers selecting this part must account for its discontinued status and plan for long-term supply chain risks. The 20-pin HTSSOP package requires specific footprint considerations during PCB layout. Designers should evaluate thermal performance given the 1.4A current capability and ensure the application environment stays within the specified -20°C to 150°C junction temperature range.

Part Context

The MPC17531 series belongs to NXP's motion control portfolio, specifically designed for low-voltage motor applications. This dual H-bridge architecture allows for versatile motor types within a small form factor. The ATEJ variant specifically denotes the HTSSOP20 package option, distinguishing it from other package styles like QFN available in the same family.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific discontinued model. Engineers should review alternative dual H-bridge drivers from NXP or other manufacturers that match the 2V-8.6V operating range and 1.4A current requirements, ensuring pin compatibility or designing adapter solutions.
