The BD6971FV from ROHM Semiconductor is a Single-Phase Brushless Motor Driver IC that has been designed for PCs, general consumer equipment of desktop PCs, and projector applications. It requires an input voltage of 3.5 - 17 V. This motor driver allows speed control using either DC or direct pulse width modulation (PWM) input and supports PWM soft switching for smoother operation. It also includes a quick start function, a current limit feature, and lock protection with automatic restart to ensure reliable performance. This motor provides a rotation speed pulse signal (FG) output, which helps in accurately monitoring the motor speed. This RoHS-compliant motor driver is available in a surface-mount package that measures 5.00 x 6.40 x 1.35 mm.
