CNTK BA6220 Datasheet

BA6220 LINEAR INTEGRATED CIRCUIT
GENERAL USE ELECTRONIC GOVERNOR
DESCRIPTION
The Contek BA6220 is a monolithic integrated circuit , developed for speed control of general use DC motors.
*Wide range of working power supply voltage range
( Vcc= 3.5V - 16V). *Very large starting torque at the low voltage. *Large permissible loss due to effective utilization of
substrate radiation. *Usable for various DC motors by means of changing
constants of the external components.
APPLICATION
*Radio cassette tape recorders
