Dear All,
I have used the following circuit to charge my 3.6v, 1500mAh NiMH (3 AA cells in series) battery. I have to cut-off battery power supply to the device while the battery is charging. Because, I have to give power supply around 7 volts to charge the battery (3 cells x 1.5v + 3v). If I connect the AC/DC power supply to the battery, this power also goes to the device and the device could have fried. So, I need to cut-off power supply to the device from Battery while the battery is being charged. Also, I cannot use any charger IC bcoz of budget. Can anyone help me solve the issue pl?
thanks
