Battery charger circuit using L200


Posted on Feb 5, 2014

A very simple battery charger circuit having reverse polarity indication is shown here. The circuit is based on IC L200. L200 is a five pin variable voltage voltage regulator IC. The charging circuit can be fed by the DC voltage from a bridge rectifier or center tapped rectifier. Here the IC L200 keeps the charging voltage constant. The charging curr

ent is controlled by the parallel combination of the resistors R2 & R3. The POT P1 can be used to adjust the charging current. This circuit is designed to charge a 12 V lead acid battery. The transistor t1, diode D3 and LED are used to make a battery reverse indicator. In case the battery is connected in reverse polarity, the reverse polarity indicator red LED D5 glows. When the charging process is going on the battery charging indicator green LED D4 glows. We aim to transmit more information by carrying articles.
