MPC17C724EP

Overview

The MPC17C724EP is a compact, monolithic dual-channel H-bridge power integrated circuit designed for driving two DC motors or one bipolar stepper motor. It operates within a supply voltage range of 2.7V to 5.5V and provides a continuous output current of 400mA per channel. The device integrates overvoltage protection, thermal shutdown, and low-side current sensing. Packaged in a 3x3 mm QFN-16 format, it supports PWM control frequencies up to 100kHz, making it suitable for portable applications requiring efficient motion control with minimal external components.

Feature Summary

• Dual-channel H-bridge architecture enabling independent control of two DC motors or a single bipolar stepper motor
• Integrated protection mechanisms including overvoltage lockout, thermal shutdown, and low-side current sensing
• Compact 3x3 mm QFN-16 package optimized for space-constrained portable designs
• Supports high-frequency PWM control up to 100kHz for precise speed regulation

Applications

• Portable three-axis pen plotters and drawing instruments
• Battery-powered robotic platforms and mobile actuators
• Precision positioning systems in desktop manufacturing equipment
• Compact automation modules requiring dual-motor synchronization

Procurement Notes

Verify the specific suffix 'EP' against official NXP documentation to confirm exact temperature grade and packaging specifications. Ensure input voltage does not exceed 5.5V to prevent damage. Confirm thermal management requirements for continuous 400mA operation in enclosed spaces. Cross-reference pinouts with the official datasheet before PCB layout finalization.

Selection Notes

Select this component when designing systems requiring dual independent motor channels within a strict footprint limit. It is appropriate for applications powered by single-cell lithium batteries or standard 5V USB supplies. Consider its 400mA continuous current rating against motor phase requirements. Evaluate the QFN-16 package suitability for your assembly capabilities regarding fine-pitch soldering.

Part Context

The MPC17C724 series belongs to NXP's portfolio of compact power drivers aimed at embedded motion control. It serves as a bridge between microcontroller logic levels and motor coil currents. The EP variant typically denotes specific environmental or packaging qualifications within the broader MPC17C724 family, often aligned with industrial or extended commercial standards.

Replacement Considerations

Consult official NXP substitution guides for verified equivalents. Generic H-bridge replacements may lack integrated protections or current ratings. Verify pin compatibility and thermal performance before swapping.
