Overview
The BD6425EFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for high-voltage applications with a supply range of 19 V to 42 V. It delivers an output current of 1.5 A and operates within a temperature range of -25°C to +85°C. The device features a low operating power supply current of 2 mA and dissipates up to 1.45 W of power. Packaged in an HTSSOP-B-28 surface-mount format, it includes two outputs and is moisture sensitive.
Feature Summary
- Fully integrated control and power stage for bipolar stepper motors
- High voltage operation capability supporting 19 V to 42 V supply ranges
- Low standby power consumption with 2 mA operating supply current
Applications
- Industrial automation equipment requiring bipolar stepper control
- Motion control systems operating within high voltage constraints
- General purpose stepping motor driver circuits
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the HTSSOP-B-28 package matches your PCB footprint requirements. Check moisture sensitivity levels (MSL) and reflow soldering profiles before assembly. Ensure the 1.5 A output current rating meets your load requirements without excessive heat sinking.
Selection Notes
Select this component when a fully integrated driver for bipolar steppers is required with a minimum supply voltage of 19 V. It is suitable for designs needing low quiescent current and robust high-voltage tolerance. Consider the HTSSOP-B-28 package size for space-constrained layouts. Verify thermal management capabilities given the 1.45 W power dissipation rating under load conditions.
