Hi,
I am designing a PCB, and it is necessary a 12 volt battery like a backup system.
I need to select a battery management to charge this battery and to know what is the level of the battery.
I know some chip of texas instruments for 4.2V batteries but I do not find anything for 12V. The specs of the battery are: 12V 1800mAh AA Ni- MH
Can anyone help me?
Thanks.
Ruben
