ROHM BD6974FV handbook
BD6974FV is a single-phase full-wave motor driver that is suitable for fan motors. This product has the following features: 1. It is compatible with external Tr pre-drivers; 2. It can control the motor speed through DC/PWM input; 3. It uses a PWM soft switching drive mode.
ROHM BD7755RFV handbook
BD7755RFV is a spindle motor, actuator coil, tilt coil, stepping motor, SA stepping motor and loading motor driver IC developed for desktop Blu-ray drive and Blu-ray recorder. Spindle driver adopts sensorless drive system, and the hall sensor (3 pieces) of the motor position detection is not needed, it is suitable for making of flexible cable conserve wiring and the reductions of external parts. The low rotation mode is built in, and stability and low-speed a rotation is achieved. The spindle, stepping and SA stepping use power MOSFET to reduce power consumption and the actuator, tilt, and loading driver use a linear BTL drive system to reduce noise.
