Overview
The BD63242EFV-E2 is a single-chip driver for three-phase full-wave fan motors, integrating power DMOS FETs. It supports sensor-less drive with sine wave output current to minimize noise and vibration. The device operates on a 5 V to 16 V supply, delivering up to 1 A output current per phase. It accepts DC or PWM speed control inputs and features rotation direction selection. Protection functions include under-voltage lockout, lock protection with automatic recovery, and high/low-speed rotation safeguards.
Feature Summary
- Integrates power DMOS FETs in a compact package for sensor-less full sine drive operation
- Supports speed control via DC voltage or PWM input signals
- Includes built-in protection mechanisms such as under-voltage lockout and automatic recovery from lock conditions
Applications
- Fan motor drivers
- Three-phase brushless DC motor applications
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the HTSSOP-B-16 package dimensions align with your PCB footprint. Confirm humidity sensitivity handling procedures are followed during assembly to prevent damage.
Selection Notes
Select this component for applications requiring low-noise, sensor-less control of three-phase fans. It is suitable where space constraints favor an integrated solution over discrete drivers. Verify that the required operating temperature range of -40°C to +100°C meets environmental conditions. Ensure the 1 A current rating suffices for the target motor load.
Part Context
This part belongs to ROHM's series of three-phase brushless DC motor drivers. It is designed for general-purpose fan applications rather than automotive use. The device simplifies motor control by combining logic and power stages, reducing external component count compared to discrete solutions.
Replacement Considerations
Check for direct substitutes within the BD63242 family or other ROHM sensor-less drivers with similar voltage and current ratings. Verify package compatibility before substitution.
