Overview
The BD6422EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor, designed for industrial and automotive applications. It operates within a supply voltage range of 19 V to 42 V and delivers an output current of 1 A. The device features a low operating power supply current of 2 mA and supports a maximum power dissipation of 4 W. It is housed in a surface-mount HTSSOP-B-24 package and functions reliably across an operating temperature range from -25 °C to +85 °C.
Feature Summary
- Integrated bipolar stepper motor driver architecture supporting parallel interface control
- High-voltage operation capability with integrated protection mechanisms
- Low quiescent current consumption for energy-efficient system design
- Compact surface-mount packaging suitable for automated assembly processes
Applications
- Industrial automation equipment requiring precise motion control
- Automotive systems utilizing stepper motors for actuation
- General-purpose bipolar stepper motor drive circuits
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and humidity sensitivity level prior to storage and handling. Ensure the HTSSOP-B-24 package dimensions match your PCB footprint requirements. Validate that the 19 V to 42 V input range aligns with your system power supply specifications before integration.
Selection Notes
Select this component when a dedicated bipolar stepper driver is required for voltages up to 42 V. Consider the 1 A output current limit and 4 W thermal dissipation capacity for load matching. The HTSSOP-B-24 package dictates specific PCB layout constraints. Verify compatibility with parallel control interfaces and ensure the -25 °C to +85 °C operating range meets environmental demands.
