BD63242FV-E2

Overview

The BD63242FV-E2 is a three-phase full-wave fan motor driver by ROHM Semiconductor, designed for sensor-less brushless DC motors. It operates on a 5 V to 16 V supply with a maximum output current of 1 A and quiescent current of 6.6 mA. The device supports frequencies from 10 kHz to 50 kHz and features an output voltage of 400 mV. It functions within a temperature range of -40°C to +100°C in a 16-pin SSOP-B package.

Feature Summary

• Integrates power DMOS FETs for compact sensor-less sine drive operation
• Supports speed control via DC voltage or PWM input signals
• Includes protection mechanisms such as under-voltage lockout and automatic recovery lock protection

Applications

• Fan motor drivers
• Three-phase brushless DC motor applications
• General type driver circuits

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm pin compatibility and electrical characteristics. Ensure the 16-SSOP-B package matches the target PCB footprint. Confirm that the sensor-less architecture aligns with the mechanical design requirements for the intended fan application.

Selection Notes

Select this component for applications requiring low-noise, low-vibration operation through sine wave output currents. It is suitable for designs needing direction management and rotation speed pulse output (FG, 1/2FG). Verify that the 1 A output current capacity meets the load requirements without exceeding thermal limits.
