BD6383EFV-E2

Overview

The BD6383EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor, designed for applications requiring precise motion control. It operates within a power supply voltage range of 10 V to 28 V and delivers an output current of 1 A. The device supports step resolutions of 1, 1/2, and 1/4 steps. It features a 40-pin HTSSOP-B package with dimensions of 13.6 x 5.4 x 0.85 mm. The component functions across a temperature range of -25°C to +75°C, with a junction temperature limit of 150°C. It includes integrated protection circuits such as thermal shutdown and overcurrent protection.

Feature Summary

• Integrated DMOS parallel output configuration for efficient bipolar stepper motor driving
• Built-in safety mechanisms including thermal shutdown (TSD), overcurrent protection (OCP), and under-voltage lockout (UVLO)
• Supports multiple step resolution modes including full, half, and quarter stepping for flexible control precision

Applications

• General-purpose stepper motor control systems
• Industrial automation equipment requiring precise positioning
• Motion control modules in consumer electronics

Procurement Notes

Verify the component status before integration, as this part is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory levels meet project requirements since future production may be limited. Ensure compatibility with the 40-pin HTSSOP-B footprint during PCB layout finalization. Check datasheet revisions for any updates to electrical characteristics or pin definitions prior to ordering.

Selection Notes

Select this driver when a compact solution with integrated power stages is required for bipolar stepper motors. Consider the 1 A output capability against load requirements. Evaluate the 40-pin package size constraints against available board space. Verify that the 10-28 V operating range aligns with the system power supply architecture. Assess thermal management needs given the package type and power dissipation limits.

Part Context
