FAN8082 (KA3082N)
Bi-directional DC Motor Driver
Features
Built-in brake function for stable brake characteristics. Built-in element to absorb a surge current derived from changing motor direction and braking motor drive. Motor speed control by an external voltage. Stable motor direction change. Interfaces with CMOS devices. Built-in the thermal shut down circuit (165°C). Low standby current. (6.5mA)
Description
The FAN8082 is a monolithic integrated circuit designed for driving bi-directional DC motor with braking and speed control, and it is suitable for the loading motor driver of VCR, CDP, and TOY systems. The speed control can be achieved by adjusting the external voltage of the speed control pin. It has two pins of logic inputs for controlling the forward/ reverse and braking.
8-DIP-300
Typical Applications
Compact disk player (CDP) tray or changer Low current DC motor such as audio or video equipment. General DC motor
