Bi-directional DC Mo tor Driver
www.fairchildsemi.com
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 a n exter na l volt age.
• Stable motor dir e c ti on ch a ng e.
• 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
