Overview
The BD6385EFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for general-purpose applications. It operates within a supply voltage range of 10 V to 28 V and delivers an output current of up to 1.5 A. The device supports step resolutions of full, half, and quarter steps. It features a 40-pin HTSSOP-B package with exposed pad for thermal management. Operating temperature ranges from -25°C to +75°C, with junction temperatures reaching up to 150°C. The driver includes integrated protection circuits such as overcurrent and thermal shutdown.
Feature Summary
- Integrated DMOS power stage with low on-resistance for efficient bipolar drive
- Supports full, half, and quarter step resolution modes
- Built-in protection functions including overcurrent and thermal shutdown
- Single power supply input simplifies system design
Applications
- General purpose stepper motor control systems
- Industrial automation equipment
- Office automation devices
Procurement Notes
Verify the complete part number including the suffix E2 when ordering to ensure correct specifications. Confirm package type HTSSOP-B-40 matches your PCB footprint requirements. Check moisture sensitivity level (MSL 3) and storage conditions if components are not used immediately. Ensure supply voltage stays within 10 V to 28 V range during operation.
Selection Notes
Select this component for applications requiring a compact bipolar stepper driver with integrated power stages. Consider the 40-pin HTSSOP-B package for surface mount assembly. Evaluate thermal dissipation needs given the exposed pad design. Compare output current capabilities against motor requirements to ensure adequate performance margins.
Part Context
This part belongs to the BD6385 series of bipolar stepper motor drivers by ROHM Semiconductor. It is designed for general-purpose motion control applications. The device integrates control logic and power output stages in a single package. It offers a balance of performance and simplicity for standard stepper motor driving tasks.
Replacement Considerations
BD6385EFV is the base part number without the E2 suffix. Verify pin compatibility and electrical specifications before substitution. Ensure any replacement matches the required voltage and current ratings.
