PRELIMINARY
SERVO MOTOR CONTROLLER
DESCRIPTION
The AA51883 is an integrated circuit to be applied on servo motor of radio controlled
operation. It provides some flexible functions to tune the servo. External PNP driver will be
chosen for servo motor application.
FEATURES
• Internal output NPN power transistor.
• Adjustable dead band range control by external capacitor.
• Fixed pulse width setting to provide start-up power and speed control
• Incorporates a protection circuit for "H-Bridge" driving configuration
AA51883
APPLICATIONS
• Servo motor control.
• Radio controlled car, boat, and airplane.
• IA products (such as air-condition).
• Remote positioning.
