Overview
The MPC17531ATEJ is a dual H-bridge motor driver IC from NXP, designed for low-voltage applications. It supports bipolar stepper motors and brushed DC motors with a supply voltage range of 2V to 8.6V. The device integrates internal control logic, a charge pump, gate drivers, and high-current, low RDS(on) MOSFET output circuitry. It operates within a junction temperature range of -20°C to 150°C and features a 20-pin HTSSOP package.
Feature Summary
- Integrates internal control logic, charge pump, and gate drive for simplified design
- Features high current, low RDS(on) MOSFET output circuitry
- Capable of driving single two-phase stepper or two brushed DC motors
Applications
- Bipolar stepper motor control
- Brushed DC motor control
- Battery-powered applications
Procurement Notes
Verify component authenticity through authorized NXP distributors or official channels. Confirm the specific suffix 'ATEJ' corresponds to the 20-pin HTSSOP tray packaging. Check for End-of-Life status as historical data indicates discontinuation. Ensure compliance with RoHS and REACH requirements before integration into final products.
Selection Notes
Select this part for low-voltage motor control systems requiring integrated power and logic. Consider the 20-pin HTSSOP package for space-constrained designs. Evaluate thermal performance given the 150°C junction limit. Compare against alternative packages like QFN if different pinout or thermal characteristics are required for the specific application layout.
Part Context
This component belongs to the MPC17531 family of dual H-bridge motor drivers. It provides a complete solution for driving small motors by combining control logic with power stages. The ATEJ variant specifically denotes the HTSSOP package option within the product line, offering a surface-mount solution for industrial and consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The MPC17531ATEJ is listed as End of Life. Designers should consult NXP directly for current availability or recommended cross-references.
