BD6423EFV-E2

Overview

The BD6423EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 19 V to 42 V and delivers an output current of 1.0 A per phase. The device features a built-in translator circuit for CLK-IN control, supporting full, half, and quarter step modes with mix decay control. Designed for surface mount applications, it utilizes an HTSSOP-B-24 package. The component functions within an operating temperature range of -25°C to +85°C and has a power dissipation rating of 4 W.

Feature Summary

Integrates a PWM constant current controllable two H bridge driver architecture
Includes a built-in translator circuit enabling direct CLK-IN control
Supports multiple stepping modes including full, half, and quarter steps
Features mix decay control for optimized motor performance

Applications

Bipolar stepper motor control systems
Motion control applications requiring precise positioning
Industrial automation equipment drivers

Procurement Notes

Verify the specific suffix E2 against the official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure thermal management solutions accommodate the 4 W power dissipation in the HTSSOP-B-24 package. Confirm humidity sensitivity handling procedures are implemented during assembly to prevent moisture-induced damage.

Selection Notes

Select this component when a high-voltage bipolar driver up to 42 V is required. The integrated translator simplifies interface logic by accepting clock inputs directly. Consider the 1.0 A output capability and the specific HTSSOP-B-24 footprint constraints. Verify that the application environment remains within the specified -25°C to +85°C operating temperature range.

Part Context

This part belongs to the BD6423EFV series of silicon monolithic integrated circuits designed specifically as bipolar stepping motor drivers. The series focuses on providing analog and PWM control capabilities within a compact surface-mount form factor. It serves as a dedicated solution for driving bipolar stepper motors without requiring external complex driver circuitry.
