BD63620AEFV-E2

Overview

The BD63620AEFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for applications requiring precise motion control. It features a maximum power supply voltage of 28 V and supports a load voltage range of 19 V to 28 V. The device delivers a continuous output current of 2 A with a peak current capability of 2 A. It operates within an ambient temperature range of -25°C to +85°C and consumes a typical operating supply current of 1.3 mA. The IC is housed in a 24-pin HTSSOP-B package with dimensions of 7.8 x 7.6 mm and a thickness of 1.0 mm. It includes a single power supply input configuration and utilizes a CLK-IN interface for step control.

Feature Summary

• Supports full step, half step, and quarter step excitation modes via built-in DAC
• Allows arbitrary setting of fast decay and slow decay ratios for optimized motor control
• Utilizes a CLK-IN drive method for simplified input interfacing
• Features a single power supply input design to enhance system integration convenience

Applications

• Bipolar stepping motor control systems
• Precision motion control devices
• Industrial automation equipment
• Office automation machinery

Procurement Notes

Verify the specific suffix E2 when ordering to ensure compatibility with RoHS standards and lead-free manufacturing processes. Confirm that the application environment remains within the specified operating temperature range of -25°C to +85°C. Ensure the power supply voltage does not exceed the maximum rating of 28 V to prevent device damage. Check humidity sensitivity requirements during storage and handling procedures.

Selection Notes

Select this component for bipolar stepper motor applications requiring up to 2 A output current. Consider the HTSSOP-B-24 package size for PCB layout constraints. Evaluate the need for mixed decay function capabilities if smooth motor operation is critical. Verify that the system can accommodate the single power supply input architecture.
