hi all...
i have made a small circuit using 89s52 and connected 7805 input to 7.4v 2200 mah li-ion battery to get output of 5v which is futher connected to 89s52. but my problem is it consumes a lot of power. my 2200 mah battery gets drained in 4 days even my circuit is in off state only 89s52 being on.
i powered my 89s52 directly to the 7.4v battery using 7805 connecting only +5v and GND to 89s52 to check if my microcontroller consumes the power or not.but yes its the only my 89s52 who consumes the power. what should me done to stop my controller to consume it.
- - - Updated - - -
and also to cross check my circuit... i again connected my 7.4v battery using 7805 to my circuit removing my 89s52... but voltage is stable....
so its now confirmed that its the only 89s52 who consumes my power
