Overview
The BD63524AEFV-E2 is a micro-stepping stepping motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 8 V to 28 V and delivers an output current of 2.5 A. The device features two outputs and supports surface mount installation in an HTSSOP-B-28 package. It functions within a temperature range of -25°C to +85°C, with a power dissipation rating of 4.7 W and a quiescent current of 2 mA.
Feature Summary
- Supports micro-stepping control for precise motion management
- Integrates dual-channel output drivers for bipolar motor applications
- Designed for low standby power consumption during operation
Applications
- Precision positioning systems requiring smooth motor rotation
- Automated equipment utilizing bipolar stepper motors
- Motion control modules in industrial automation devices
Procurement Notes
Verify the specific suffix E2 against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure that the HTSSOP-B-28 package dimensions align with the target PCB layout. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent component damage during manufacturing processes.
Selection Notes
Select this component when a 2.5 A drive capability is required for bipolar stepper motors operating between 8 V and 28 V. The HTSSOP-B-28 package offers a compact solution for space-constrained designs. Consider the 4.7 W power dissipation limit and ensure adequate thermal management is integrated into the system design to maintain reliable operation within the specified temperature range.
Part Context
This part belongs to the BD63524 series of micro-stepping motor drivers from ROHM. It is designed specifically for applications requiring high-resolution step control. The device integrates necessary logic and power stages into a single chip, simplifying the design process for stepper motor control circuits while maintaining efficiency and precision in motion execution.
Replacement Considerations
The BD63524AEFV is listed as an alias for this component. Verify functional equivalence and package compatibility before substitution. No other direct substitutes are confirmed in the provided data.
