PRELIMINARY ■ DESCRIPTION
AA51881
SERVO MOTOR CONTROLLER
The AA51881 is a BJT integrated circuit to be applied on servo motor control applications. The built-in voltage regulator provides the AA51881 with extremely stable output voltage. It also incorporates a linear one-shot and pulse-width demodulator for improved positional accuracy. ■ FEATURES Built-in voltage regulator. Larger driving capability. Internal output NPN power transistor. Adjustable dead band range control. Incorporates a protection circuit for "H-Bridge" driving configuration. Small outline package. ■ APPLICATIONS Servo motor control. Radio controlled car, boat, and airplane. IA products (such as air-condition). Remote positioning. ■ BLOCK DIAGRAM
