Hi,
I am looking for information about the coulomb counter and its capability to measure rapid consumption burst (few ms).
Sampling rate is provided for ADC but I can't find information for the Coulomb counter.
Coulomb counter is described in page 8 of Datasheet :
"The differential voltage between SENSEP and SENSEN is first low-pass filtered and then applied to a precision coulomb counter.
The coulomb counter integrates and then digitizes the differential voltage, incrementing and decrementing the Accumulated Charge Register (ACR) as needed."
Can you provide any information regarding :
- Low-Pass filter cutting frequency
- Coulomb counting sampling frequency
- Global Vsense maximum bandwidth
Best regards,
Laurent
