Overview
The BD63282EFV-E2 is a three-phase full-wave fan motor driver by ROHM Semiconductor, integrating power DMOS FETs in an HTSSOP-B-20 package. It supports 5 V to 16 V supply voltage with a maximum output current of 1 A and operates between -40°C and +100°C. Designed for brushless DC motors using three Hall sensors, it enables stable startup and sine wave drive for low noise. The IC features DC/PWM speed control, rotation direction selection, and protection functions including under-voltage lockout, lock protection, and high/low-speed safeguards.
Feature Summary
- Integrates power DMOS FETs for compact three-phase motor driving
- Enables stable startup via three-Hall sensor rotor position detection
- Supports sine wave output for reduced acoustic noise and vibration
- Provides comprehensive protection against under-voltage, lock, and speed extremes
Applications
- Fan motor drives in home appliances
- Paper feeding mechanisms in office equipment
- Multi-prism devices in imaging systems
- Optical disc drive (ODD) spindle motors
Procurement Notes
Verify the suffix E2 indicates RoHS compliance and lead-free status per ROHM specifications. Confirm HTSSOP-B-20 packaging matches design requirements. Check moisture sensitivity level handling instructions before reflow soldering. Ensure supply voltage range aligns with system rails. Validate thermal performance within the specified operating temperature limits.
Selection Notes
Choose this part when three-Hall sensor commutation is required for reliable BLDC startup. Select for applications needing sine wave drive to minimize noise. Consider if 1 A output current meets load demands. Verify compatibility with DC or PWM speed control inputs. Ensure package size fits PCB constraints compared to sensorless alternatives like BD63242EFV-E2.
Part Context
Part of ROHM’s BD632 series for three-phase brushless DC motor drivers. Differentiated from sensorless variants by requiring three Hall elements for position feedback. Offers fixed or auto lead angle control for optimized torque. Targets general-purpose motor control where stability and low noise are prioritized over sensorless complexity.
Replacement Considerations
BD63242EFV-E2 serves as a sensorless alternative but lacks Hall-based startup stability. Direct pin-to-pin replacement requires verifying control logic compatibility. Ensure application does not mandate sensorless operation before substituting.
