Battery Monitoring and Microprocessor

I doubt it but the data sheet is your friend.

Hi, So, Why the data sheet is my friend?

John

One more thing that I forgot to mention is that I am using the following battery

John

The day has not yet arrived where an ADC and microprocessor are required to perform this task, unless the task is actually homework, or the microprocessor is already there.

If the latter is the case, then use the part that is already present.

RL

Its not home work but the microprocessor is already there. But I can add the voltage monitor chip to the board if I have some prove that it will be more power efficient than the microprocessor.

John

It is not. Many uC can power-off the A2D subsystem. By the way, turning on an LED might just klll the already dying battery.

Actually this a wireless system. So, the battery will be monitored at the transmitter end and the LED will be on the receiving end.

Regards, John

Kind of failed to mention that in you first three posts, didn't you ?

You would think that this would have been kind of important, don't you ?

So, start over and specify what the current transmitter looks like and what the current receiver looks like.

Guessing what you'll come up with next isn't helping anyone.

don

Google for "Microprocessor Supervisory Circuit"+2.5V.

RL

Because it will contain the information you need.
