MCZ33991EGR2

Overview

The MCZ33991EGR2 is a fully integrated bipolar stepper motor driver manufactured by NXP USA Inc. It operates within a voltage range of 4.5V to 5.5V and utilizes SPI communication for control. The device integrates both the control logic and power stage in a single unit, housed in a 24-SOIC package. Pinout assignments include dedicated connections for sine and cosine signals, ground, power supply, and SPI interface lines such as CS, SCLK, SI, and SO.

Feature Summary

• Fully integrated driver combining control and power stages
• SPI-based digital interface for command and status exchange
• Designed specifically for bipolar stepper motor applications

Applications

• Motorcycle Engine Control Unit (ECU)
• Small engine control systems
• Scooter and three-wheeler management modules

Procurement Notes

Verify component authenticity through authorized distributors. Confirm that the obsolete status does not impact long-term supply chain stability for existing designs. Ensure compatibility with 4.5V-5.5V operating ranges before integration into final assemblies.

Selection Notes

Select this component when a compact, low-voltage solution for bipolar stepper motors is required. The integrated nature reduces external component count. Verify SPI interface compatibility with the host microcontroller. Consider the 24-SOIC footprint for PCB layout constraints.
