Overview
The BD63910MUV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor. It features a rated supply voltage of 36V and a rated output current of 1.0A per phase. The device supports two input interface modes: CLK-IN and PARA-IN. It incorporates an internal Digital-to-Analog Converter (DAC) for excitation control. The component operates within a temperature range of -40°C to +105°C and is housed in a VQFN-28 surface-mount package.
Feature Summary
- Supports selectable CLK-IN and PARA-IN driving modes for flexible system integration
- Integrates an internal DAC for precise excitation mode control
- Designed for low power consumption applications
Applications
- Bipolar stepper motor control systems
- Precision motion control devices
- Industrial automation equipment
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with RoHS standards and environmental requirements. Confirm that the VQFN-28 package dimensions align with the target PCB footprint. Ensure the selected driving mode matches the host controller's interface capabilities before finalizing procurement.
Selection Notes
Select this component when a 36V rated supply and 1.0A continuous output current are required for bipolar stepper motors. The choice between CLK-IN and PARA-IN modes should be determined by the host microcontroller's available interfaces. Consider the thermal performance within the -40°C to +105°C operating range during design validation.
