Overview
The BD63740FM-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for industrial automation. It features a rated power supply voltage of 36V and a rated output current of 4.0A. The device utilizes a PWM constant current drive method with a CLK-IN interface. It includes an internal DAC to support various excitation modes, including full step operation. The component operates within a temperature range of -25°C to +85°C and is housed in a 36-pin HSOP-M package.
Feature Summary
- Bipolar low-consumption driver utilizing PWM constant current control
- Integrated digital-to-analog converter (DAC) for flexible excitation mode selection
- Clock-input driven interface for precise step control
Applications
- Industrial automation projects requiring moderate-torque stepper motors
- Compact camera mechanisms
- General-purpose bipolar stepper motor control systems
Procurement Notes
Verify the specific ordering suffix and package variant against the official ROHM datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm that the 36V rating and 4.0A current capacity align with your motor specifications. Check for any regional compliance certifications required for your target market before finalizing procurement.
Selection Notes
Select this component when a bipolar stepper motor requires a 36V supply and up to 4.0A continuous current. It is suitable for applications needing PWM current regulation and multiple excitation modes via internal DAC. Ensure the system design supports the CLK-IN driving method and fits within the -25°C to +85°C operating temperature range.
Part Context
This part belongs to the BD63740 series of stepper motor drivers by ROHM Semiconductor. It is specifically engineered as a low-power solution for demanding industrial applications. The FM-E2 designation indicates the specific package and environmental grade, distinguishing it from other variants in the family.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users should consult ROHM technical support or official distributor catalogs for direct replacements.
