BD64220EFV-E2

Overview

The BD64220EFV-E2 is a fully integrated bipolar stepper motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 8 V to 46.2 V and delivers an output current of 1.4 A per channel. The device features four half-bridge outputs controlled via a PWM interface. Designed for surface mount installation, it utilizes a 28-pin HTSSOP-B package. The component functions reliably across an operating temperature range from -25°C to +85°C with a typical quiescent current of 2 mA.

Feature Summary

• Fully integrated control and power stage for bipolar stepper motors
• Supports PWM interface for precise speed and position control
• Includes four independent half-bridge drivers

Applications

• Bipolar stepper motor control systems
• Industrial automation equipment
• Office automation devices

Procurement Notes

Verify the specific suffix E2 against the official datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS compliance status through the manufacturer's documentation. Check the lifecycle status as NRND (Not Recommended for New Designs) to assess long-term availability risks before finalizing procurement plans.

Selection Notes

Select this component when driving bipolar stepper motors requiring up to 1.4 A per phase. Ensure the application voltage stays within the 8 V to 46.2 V range. Verify that the thermal management solution supports the HTSSOP-B package in the target environment. Consider the NRND status if designing for long-term production runs.
