I need the concept behind the mobile charger, particularly tell me how the LED Indication will be their before chargering their will be RED LED after Charge gets over, How that green LED Glow...
Can you guys please explain me the hole concept behind this....
Hello,
The circuit in the charger monitors the charging current / voltage level across the battery. Once the battery is fully charged, the charging current will be very less or even zero and the voltage across the battery will be max. An ADC can be used to measure the analog input and interfaced to a microcontroller for better performance.
