MPC17533EV

Overview

The MPC17533EV is a dual H-bridge integrated circuit designed for motor control applications. It incorporates internal control logic, a charge pump, gate drivers, and high-current low Rds(on) MOSFET output circuits. This integration allows the device to drive either a single two-phase stepper motor or two brushed DC motors efficiently within a compact form factor.

Feature Summary

• Integrates internal control logic with charge pump and gate driver circuitry
• Features high-current, low on-resistance MOSFET output stage
• Capable of driving a single two-phase stepper motor
• Supports simultaneous operation of two brushed DC motors

Applications

• Driving single two-phase stepper motors
• Controlling two independent brushed DC motors
• Evaluation board implementation via FRDM-17533EV-EVB

Procurement Notes

Verify the specific suffix (EL) against official documentation to confirm package type and temperature range. Ensure compatibility with the intended motor load current requirements before procurement. Cross-reference the part number with NXP Semiconductors official databases to confirm current production status and availability.

Selection Notes

Select this component when a dual-channel motor solution is required in a single package. It is suitable for designs needing to drive either one stepper or two DC motors without external discrete power stages. Consider the internal charge pump requirement for gate drive voltage when designing the supply rails.

Part Context

This IC belongs to NXP's motor driver portfolio, often utilized in evaluation platforms like the FRDM-17533EV-EVB. It serves as a core power stage component for motion control systems, simplifying design by integrating high-side and low-side drive capabilities into one unit.

Replacement Considerations

Consult official substitution lists for equivalent dual H-bridge drivers. Verify pinout compatibility and thermal performance if replacing with similar devices from other manufacturers.
