UTC AN6651 LINEAR INT E G R A TED CIRCUIT

MOTOR SPEED CONTROL
CIRCUIT

DESCRIPTION

The UTC AN6651 is a monolithic integrated circuit
designed for the rotating control of a compact DC motor
which is used for a tape recorder, recorder player etc.

FEATURES

*Wide operating supply voltage: Vcc=3.5V ~ 14.4V
*Small four-lead plastic packer for compact motor.
*Few external components
*Stable low reference voltage (1.0V, typical)
*Wide motor speed setting
*Reverse voltage protection circuit built-in
