Introduction
BD7755RFV are ICs, developed for the spindle motor, actuator coil, tilt coil, stepping motor, SA stepping motor and the loading motor drive of the desktop Blu-ray drive and Blu-ray recorder. Spindle driver adopted 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.
Features
- The low-speed stability rotation is achieved with built-in the low rotation mode.
- The hall sensor is unnecessary according to 3 aspect sensorless drive system.
- The spindle motor driver achieves stability high speed start by ROHM's own energizing method.
- Highly effective spindle, stepping and SA stepping is achieved by PWM control driver. And the output current detection resistance of stepping and SA stepping is unnecessary by built-in internal detection circuit.
- The actuator, tilt and loading driver achieve low noise by using linear BTL drive system.
- ON/OFF of loading and other channels, brake mode of spindle driver and standby mode are selectable by the two control terminals.
- Built-in thermal-shut down circuit.
- Improved heat radiation efficiency utilizing HTSSOP package.
Applications
- For desktop Blu-ray drive
