hi.. I have programmed PIC16f676 for charging 6 cell(7.2) volts NiCd Battery... The only problem remaining is..
to make constant current soutce of 1.2Amps (can be changed), such that if enabled (by applying 1 from Controller port pin) , battery should be charged with this constant current and when I disable it (by applying zero from a port pin), it should behave like an open switch as if it were not present (Nothing goes in, nothing goes out or as if battery were disconnected)... I have I/P Voltages of about 12Volts, the voltage that appears at the O/P of this current source should be fixed irrespective of its I/P voltage..
Kindly, guide what to do... or give me exact scematic for that with actual values of components...
Regards..
