Description Most mobile chargers do not have current/voltage reguLation or short-circuit protection. These chargers provide raw 6-12V DC for charging the battery pack . Most of the mobile phone battery packs have a rating of 3.6V, 650 mAh. For increasing the life of the battery, slow charging at low current is advisable. Six to ten hours of charging at 150-200mA current is a suitable option. This will prevent heating up of the battery and extend its life. The circuit described here provides around 180mA current at 5.6V and protects the mobile phone from unexpected voltage fluctuations that develop on the mains line. So the charger can be left ‘on’ over night to replenish the battery charge . The circuit protects the mobile phone as well as the charger by immediately disconnecting the output when it senses a voltage surge or a short circuit in the battery pack or connector. It can be called a ‘middle man’ between the existing charger and the mobile phone. It has features like vol...

This post share about Mobile Phone charger circuits, previously you can see other Phone Battery Charger Circuit   or Charger Circuit  . This Charger ciruit use to charging phone battery using IC 7805 for plus voltage regulator or & 7905 for min voltage regulator.  Below is a schematic circuit adapter, power supply , or battery charger (for gadgets, mobile phones , MP4player, smartphone) that is equipped with a 5V voltage stabilizer : Diode Bridge diode bridge, known as a diode bridge is used for the rectifier circuit current ( rectifier ) from AC to DC . to make the diode bridge properly you need to know the type of diode to be used, to suit your needs. example: to make the power supply 12 Volt 3 ​​Ampere diode type 1N5401 is needed, for more detail how to choose the right type of diode to the adapter. Voltage stabilizers are commonly used are the 78XX or 79XX type LM, XX indicates the maximum voltage output is generated. see the example in the circuit schem...
