Overview
The BD68620EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor. It utilizes PWM current control and DMOS technology to drive stepping motors with a rated output current of 2.0A. The device operates within a power supply voltage range of 19V to 28V, with a maximum load voltage rating of 36V. It supports step resolutions of full, half, and quarter steps. The component is housed in an HTSSOP-B-24 surface-mount package and functions within an operating temperature range of -25°C to +85°C.
Feature Summary
- Bipolar low-consumption driver utilizing PWM current for operation
- Supports full, half, and quarter step resolution modes
- Integrated protection circuits including thermal shutdown and overcurrent protection
Applications
- General-purpose stepping motor control systems
- Industrial automation equipment requiring bipolar stepper drivers
- Motion control applications with single power supply input
Procurement Notes
Verify the specific suffix EFV-E2 against the manufacturer's datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the HTSSOP-B-24 package dimensions and thermal requirements. Confirm that the application voltage remains within the 19V to 28V operational range specified for this part number.
Selection Notes
Select this component for applications requiring a bipolar stepper driver with integrated PWM current control. It is suitable for designs needing full, half, or quarter step resolution without external microstepping circuitry. Consider the 2.0A output capability and 36V absolute maximum rating when sizing the power supply and motor coils.
Part Context
This part belongs to ROHM's series of bipolar stepper motor drivers designed for low consumption and high reliability. It integrates DMOS output stages to handle the required load currents efficiently. The device simplifies system design by combining driver logic and power stages in a compact surface-mount package.
Replacement Considerations
Consult official ROHM documentation for direct substitutes. Verify electrical parameters such as output current, voltage ratings, and package type before considering alternative components from other manufacturers.
