Hi,
I'm using the STC3100 chip to get the coulomb used from the battery, using the REG_CHARGE_LOW registers,

on the new board, I want to move to STC3117, but I don't see this register,
Does anyone know how I can get this value?

 

Thanks

Shamir

What about REG_SOC ?

As I understand, this is % of the battery,
I can't get the "used" coulomb value.

But you can easily work that out from the battery % , surely?

Hi,
Thanks for the replay,
I'm not sure I can get the coulomb reading in this mode,
it seems that I need to set the battery information in the chip, and the chip calculates the % which I get.
this is not what I need,

but, because of the footprint of the device, which requires the use of blind VIA which increases the board price - I will not use this chip, and use the SCT3100.

thanks a lot for the answers and help
