As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply's rated voltage of 36V and rated output current of 1.0A～2.2A.

BD6961F is a single-phase full-wave motor driver for fan motor. It features PWM speed control and soft switching function.

This file introduces the features of BD6370GUL, BD6758MWV and BD6758KN, including the appearance size, package type, drive type, resistance and other.

BD6757KN and BD6889GU stepper motor drivers provide 6 full-ON drive H-bridge channels and 1 linear constant-current drive H-bridge channel. Stepping motors can be used for the auto focus, zoom, and iris, making it possible to configure a sophisticated, high precision lens drive system. ROHM’s motor drivers are both compact, multifunctional, and enable advanced features such as lens barrier and anti shock.

This document introduces the System Lens Driver series for digital cameras and single-lens reflex cameras. It provides multiple models of drivers, including full-ON drive H-bridge channels and linear constant-current drive H-bridge channels, suitable for driving autofocus, zoom, or iris. Various types of shutter drivers are also offered, including full-ON type, high-precision linear constant current type, and high-efficiency PWM constant current type.

The document describes a single-phase full-wave motor driver for fan motors. It features speed control through DC/PWM input, current limit circuit, and PWM soft switching drive.

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.

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.
