MC34921AER2

Overview

The MC34921AER2 is a fully integrated motor driver IC designed for bipolar stepper and brushed DC motors. It features a full H-bridge configuration with two dual low-side drivers, supporting output currents of 1.5A and 4.5A. The device operates on a power supply voltage range of 4.8 V to 5.2 V and handles load voltages from 0 V to 38 V. It utilizes a serial interface for control and is housed in a 64-LQFP EP (10x10) package with exposed pads for surface mount installation. The component functions within an operating temperature range of 0°C to 70°C.

Feature Summary

Fully integrated design combining control logic and power stages
Supports both bipolar stepper and brushed DC motor types
Full H-bridge output configuration with dual low-side drive capability
Serial interface for simplified system connectivity

Applications

Bipolar stepper motor control systems
Brushed DC motor drives
General purpose motor applications

Procurement Notes

Verify the specific ordering suffix 'E' and 'R2' against official NXP documentation to confirm tape-and-reel packaging and lead-free status. Ensure the 64-LQFP EP package dimensions match the PCB footprint requirements. Confirm that the 4.8V–5.2V supply range aligns with the system's power architecture before procurement.

Selection Notes

Select this component when a single-chip solution for controlling bipolar stepper or brushed DC motors is required. The integrated nature reduces external component count compared to discrete driver solutions. Consider the 38V load voltage limit and current ratings relative to the target motor specifications. The serial interface requirement must be compatible with the host microcontroller's communication capabilities.

Part Context

This part belongs to the PMIC - Motor, Bridge Drivers category within NXP's portfolio. It serves as a dedicated actuator control solution, distinct from general-purpose logic or processing devices. The device integrates power switching elements directly with control circuitry, positioning it between simple logic gates and complex multi-axis motion controllers.
