BD63888MUV-E2

Overview

The BD63888MUV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor, designed for surface-mount applications in the VQFN-36 package. It operates within a supply voltage range of 8 V to 28 V and delivers an output current of 1.2 A across four half-bridge outputs. The device features a parallel interface and maintains a low operating supply current of 5 mA. It functions reliably within a temperature range of -25°C to +85°C, supporting high-reliability motion control systems requiring precise bipolar stepper motor actuation.

Feature Summary

• Integrates four half-bridge drivers for complete bipolar stepper motor control
• Supports parallel interface communication for straightforward digital control
• Designed with low consumption characteristics to minimize power usage

Applications

• Bipolar stepper motor actuation in industrial automation equipment
• Motion control systems requiring precise positioning
• Embedded devices utilizing parallel interface motor drivers

Procurement Notes

Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with RoHS directives and environmental standards. Ensure the VQFN-36 package dimensions match the target PCB footprint. Confirm that the 8V to 28V supply range aligns with the system power design. Validate the parallel interface signal levels against the microcontroller or logic source specifications before integration.

Selection Notes

Select this component when a dedicated bipolar stepper driver with four half-bridges is required. The VQFN-36 package suits space-constrained surface-mount designs. Consider the 1.2 A output capability and 28 V maximum voltage rating relative to the motor coil requirements. The parallel interface choice dictates the control logic architecture compared to serial alternatives.
