KA3082
Bi-Directional DC Motor 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 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 KA3082 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.
10-SIP
Target Applications
• Video Cassette Recorder (VCR) Loading Motor
• Low Current DC Motor Such as Audio or Video
Equipment.
• General DC Motor
