Overview
The BD68715EFV-E2 is a bipolar stepping motor driver manufactured by ROHM Semiconductor. It features a rated power supply voltage of 36 V and a rated output current of 1.5 A. The device utilizes PWM current drive technology for efficient motor control. It is housed in a 28-pin HTSSOP-B package, designed for surface mount applications. The component operates within a temperature range of -25°C to +85°C and includes built-in protection functions such as overcurrent detection and thermal shutdown to ensure high reliability in various motion control systems.
Feature Summary
- PWM current drive mechanism for precise bipolar stepper motor control
- Integrated overcurrent detection and thermal shutdown protection circuits
- High-reliability withstand voltage design suitable for demanding environments
Applications
- Bipolar stepper motor driving in industrial automation equipment
- Motion control systems requiring high-reliability voltage withstand
- Precision positioning devices utilizing PWM current regulation
Procurement Notes
Verify the specific suffix EFV-E2 against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with 36V supply rails and 1.5A load requirements. Cross-reference pinout diagrams for HTSSOP-B-28 mounting. Confirm RoHS compliance status through manufacturer datasheets before integration into final assemblies.
Selection Notes
Select this component when bipolar stepper motors require a 36V supply and up to 1.5A output current. The HTSSOP-B-28 package suits space-constrained PCB designs. Consider the integrated protection features for applications needing robust fault handling. Verify thermal management capabilities align with the operating temperature range of -25°C to +85°C for the intended environment.
Part Context
This part belongs to ROHM's series of high-performance stepping motor drivers. It is designed for applications demanding reliable motor control with integrated safety features. The BD68715EFV-E2 variant specifically addresses needs for higher voltage operation and current capacity compared to lower-rated siblings in the family.
Replacement Considerations
Consult official substitution lists for direct replacements. Ensure any alternative maintains 36V rating, 1.5A output, and HTSSOP-B-28 footprint. Verify PWM drive compatibility and protection feature parity.
