YD6220
GENERAL USE ELECTRONIC GOVERNOR
--YD6220
DESCRIPTION
The YD6220 is a monolithic IC developed for speed control of general use DC motors.
FEATURES
*Wide range of working power supply voltage range (V
CC=
3.5V16V);
*Very large starting torque at low voltage;
*Large power dissipation allowable by using the PCB as a heat sink;
*Various DC motors can be driven by changing the external constants.
