FAN8082D
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 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 FAN8082D 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 control ling the
forward/ reverse and braking.

8-SOP-225

Typical Applications

• Compact disk player (CDP) tray or changer

• Low current DC motor such as audio or video equipment.

• General DC motor
