Overview
The BD63525AEFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor, designed for microstepping applications up to 1/16 resolution. It operates within a supply voltage range of 8 V to 28 V and delivers an output current of 2.5 A per phase. The device features a low operating supply current of 2 mA and supports power dissipation up to 4.7 W. It is housed in a 28-lead HTSSOP-B package suitable for surface mount technology. The component functions across a temperature range of -25°C to +85°C and includes two output channels for driving bipolar motors.
Feature Summary
- Supports 1/16 microstep drive resolution for precise motion control
- Integrates DMOS PWM technology for efficient bipolar motor driving
- Features low standby current consumption for energy efficiency
Applications
- Precision positioning systems requiring fine step resolution
- Automated machinery with bipolar stepper motor requirements
- Industrial equipment utilizing microstepping motion control
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging and specifications. Confirm RoHS compliance status through official documentation before integration. Check moisture sensitivity levels and storage conditions to maintain component integrity during handling and assembly processes.
Selection Notes
Select this driver when 1/16 microstepping capability and 2.5 A output current are required. Ensure the application voltage stays within the 8 V to 28 V range. Consider the 28-HTSSOP-B package size for PCB layout constraints. Verify thermal management needs given the 4.7 W power dissipation rating.
Part Context
This component belongs to ROHM's line of motor controllers and drivers, specifically categorized under PMIC solutions. It is designed for applications needing reliable bipolar stepper motor control with integrated microstepping functionality. The device complements other motion control ICs by providing high-resolution stepping capabilities in a compact surface-mount package.
Replacement Considerations
The BD63521EFV-E2 is a related variant offering similar microstepping features but with a lower output current rating of 2 A. Verify if the reduced current capacity meets specific load requirements before substitution.
