spanish battery level indicator
Would like to design a battery level detector which will output a 2bit IO to a MCU at 4 different levels.
Have seen some Voltage supervisors but they dun seem to be the ones i need,
Anyone has any experience in doing them ?
I would like to ask a question. For bandgap voltage reference, how do you use a capacitor to make this designed voltage insensitive to supply voltage variations. The design that I have done, the capacitor that I need to minimize glitch is 0.1micro and it is too big. If i put 1n, this cap has no...
