12V 10Ah and 6V SLA, Lead Acid Battery Charger Circuit Using BQ24450 IC

The primary application of the project is to replace the mechanical Potentiometer with optical encoder which is long life, accurate, smooth in operation. The simple project has been designed around LS7184 quadrature clock converter IC from LSI semiconductor, AD5220-10 Digital potentiometer from Analog Devices, and optical encoder from Burns.

High Voltage Capacitor Charger Input 21-24V Dc and Output 500V DC
