Simple Cellphone Battery Charger Circuit


Posted on Feb 6, 2014

With the advent of modern ICs, sophisticated circuits today no longer have to be complex and lengthy. The chips themselves carry most of the complex circuitry built-in and single handedly perform the desired function. Take for example the present battery operated cell phone charger circuit, which is intended for a relatively application of chargin

g a cell phone battery yet can be simply built using just a couple of passive parts along with a single active part (the IC 7805). Yes indeed, if you build the circuit which is shown, exactly as per the guidelines of the schematic, completing and getting rewarded through its service won`t be difficult at all. The input (max 35 volts) from any automobile lead acid or SMF battery is applied to the input of the circuit, instantly a regulated 5 volt output is obtained at the respective terminal of the IC via the current limiter resistor. The output must be terminated through an appropriate charging pin as used in most of the AC operated cell phone chargers.
