Hi guys,
I have a device with 4 subsystems that needs to be powered up from rechargeable batteries, the batteries needs to be charged up through a solar panel. I need + and - 9V for an opamp, 5V for the microprocessor, 3.8V for a transmisson unit and 1.2 V for the opamp input. All the volatges are DC. I need help with the batteries charger circuit and how to power up the system components using the chargeable batteries when they are full charged. Now I am thinking I need three 9V-rechargeable batteries, and use few LM 317T regulators to power up the system. I also have a 16 V solar panel with 15 ma current. but just not sure if this will solve the problem. Please, any feedback is welcome and appreciated.
Cheers!!
