Hi,
I have a LTC4150 coulomb counter on wich I changed the Rsense resistor to a 1 Ohm resistor. This means it has an maximum current of 50 mA which is fine. but I don’t realy know if my mAh per interupt is correct with the resistor. I think it is 0.00853387 mAh. The data sheet has an formula to calculate this but in this formula there is a value named Gvf and i don’t know what this should be. I used the values from sparfun Rsense and mAh/interupt to calculate the Gvf they used and used this to calculate my mAh/interupt value but i don’t know if this is correct or not.
hoop someone can help with this
I am also facing the same issue. I have a 1300 mAh battery and using the pre-installed resistance value it takes ages to discharge the battery. I want to increase the discharge speed and therefore thought to increase the Rsense resistor value to lets say 1 ohm , but then I started struggling with the ticks that I should use in the code.
I think I am not on the right track here, as I am unable to:
-
calculate the number of ticks required for my battery.
-
If I change the Rsense resistor, will it also change the number of ticks
-
If I keep the Rsense ohm to original value (0.05 ohm) and add a load to coulomb counter output, lets say an LED, will it increase the discharge speed?
Changing rsense doesn’t change how much current the board uses, you need to connect a load to the output to have more current flow through the board.
