Overview
The BD68610EFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for PWM current-driven applications. It features a rated power supply voltage of 36V and a rated output current of 1.0A. The device operates within a temperature range of -25°C to +85°C and utilizes an HTSSOP-20 package with exposed pad for enhanced thermal performance. It includes protection circuits such as overcurrent, overvoltage, and thermal shutdown.
Feature Summary
- Bipolar low-consumption driver optimized for PWM current control
- Integrated protection mechanisms including thermal shutdown and overcurrent protection
- Single power supply input capability simplifying system design
Applications
- Stepper motor control systems
- Precision motion control devices
- Automotive interior actuators
Procurement Notes
Verify the exact suffix E2 against the manufacturer's latest documentation to ensure compliance with current RoHS standards and pinout configurations. Confirm that the HTSSOP-20-EP package matches the target PCB footprint, paying attention to the exposed pad thermal requirements. Cross-reference the 36V rating with the specific application voltage headroom to ensure safe operation margins.
Selection Notes
Select this component when a compact, single-supply bipolar stepper driver is required with integrated safety features. The 1.0A output current suits moderate-load applications where space constraints favor the HTSSOP-20 form factor. Consider the CLK-IN interface compatibility if synchronous control signals are part of the system architecture.
Part Context
This part belongs to ROHM's series of stepping motor drivers, specifically engineered for efficiency and performance in compact packages. It serves as a specialized solution for controlling bipolar stepper motors in environments requiring reliable current regulation and thermal management within a small footprint.
Replacement Considerations
Check for direct substitutes within the BD686xx series or other ROHM bipolar drivers with similar 36V/1A ratings. Ensure any replacement maintains the HTSSOP-20-EP package and compatible control interfaces to avoid PCB redesign.
