BD63876EFV-E2

Overview

The BD63876EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor, designed for high-voltage applications with a supply voltage range of 19 V to 36 V. It features a peak output current capability of 2.0 A and operates within an ambient temperature range of -25°C to +85°C. The device utilizes a surface-mount HTSSOP-B-28 package with a thermal pad for efficient heat dissipation. Key electrical specifications include a maximum power dissipation of 1.45 W and a quiescent supply current of 2 mA. It supports mixed decay functions and includes integrated protection circuits for overcurrent, overvoltage, and thermal conditions.

Feature Summary

• Supports single power supply input up to 36 V for simplified system design
• Integrates CLK-IN drive method for precise step control
• Includes comprehensive protection features such as TSD, OCP, UVLO, and OVLO

Applications

• Industrial automation equipment requiring precise motion control
• Office automation devices such as printers and scanners
• Medical equipment utilizing bipolar stepper motors

Procurement Notes

Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with RoHS and REACH standards. Ensure the ordering part number matches the exact package variant and pin configuration required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm active status and any potential lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when operating voltages exceed 13.5 V or when higher current capabilities are required compared to lower-voltage series members. The HTSSOP-B-28 package offers a balance of thermal performance and footprint efficiency. Consider the CLK-IN interface requirement if synchronous clocking is preferred over parallel control signals in the target application architecture.

Part Context

This driver belongs to the BD638xxEFV series of bipolar stepper motor controllers from ROHM. It shares architectural similarities with parts like the BD63875EFV-E2 but differs in voltage ratings and specific feature sets. The series is characterized by low on-resistance DMOS outputs and integrated safety protections, targeting compact and reliable motor control solutions in consumer and industrial electronics.

Replacement Considerations

BD63875EFV-E2 is a related model within the same family; verify voltage and current compatibility before substitution.
