BQ76940: Current sampling period of BQ76940

Makoto Teramoto

Part Number: BQ76940

Hi team,

Could you tell me the sampling period of measuring current in CC?
I found the integral period of CC is 250ms, but I could not find the sampling period discription in the datasheet and FAQs.

Hi Makoto,

The clock and sampling for the current is 256 kHz or 4 us, see the data sheet block diagram and figure 9 of the application note http://www.ti.com/lit/an/slua775/slua775.pdf .

Hi,

Thank you for your quick answer !

I found the 256KHz, but I didn't think that is the sampling freq. It's so fast sampling !

Thank you again.

Regards,

Makoto Teramoto
