TECHNICAL DATA
KIA6903P
BIPOLAR LINEAR INTEGRATED CIRCUIT
DC MOTOR SPEED CONTROLLER FOR CASSETTE TAPE RECORDER SYSTEM
The KIA6903P is a monolithic IC developed for speed control of general purpose DC motors.
This IC consist of a reference
voltage generator, current multiplier, comparator and start circuit.
The IC controls the speed of a DC motor by detecting counter electromotive force from the DC motor.
FEATURES Wide Range of Working Power Supply
Voltage.
(VCC=3.
5 18V) Very Large Starting Torque at the low
Voltage.
Large Allowable Loss due to Effective Utilization of Substrate Radiation.
Usable for Various DC Motors by Means of Changing Constants of the External Components.
