Avg. Power consumption calculation
ArCoN:
Hi All 8)
Can any one help me with this.
I have a circuit that use:
30uA static
wake up 2 times/sec and uses 3.3mA for 10mS at idle
and it do some work 10 times/day and it uses 5mA for 5sec
i cant get it right, for some reason
i have a 1100mAh battery
I get around 100h in my calc and it is not right :-\
Thanks
Psi:
I got average total current draw of 98.894 uA
so 11123 hours
ArCoN:
Thanks Psi
Can you write how you did it? ;D
sleemanj:
5mA for 5s is 0.0069 mAh, 10 times a day, divide by 24 hours 0.00289 mAh in an hour
3.3mA for 10mS is 9.1666666666667e-09 mAh, twice a second for an hour is 0.066 mAh in an hour
30uA for an hour is 0.03 mAh
Total 0.0988 mAh in an hour
I come up then with 11,000 hours (rounded :-))
I am probably wrong, I'm really bad at maths.
Psi:
Here's the workings, excel file attached.
But i wouldn't trust this as correct unless someone else gets the same number.
(Edit, looks like sleemanj also got 0.0988 mAh and round 11,000 hours )
