8.9.2 Fuel Gauge
The fuel gauge circuit enables remaining capacity estimation of the battery by tracking the net current flow into and out
of the battery using a voltage-to-frequency converter.
Voltage-to-Frequency Converter
The voltage-to-frequency (VFC) converter constantly monitors the voltage drop across an external current sense
resistor Rsense connected in series between the negative battery terminal and ground. The use of an additional
external RC lowpass filter is highly recommended. Using two 4.7k
Ω resistors (Rfilt1,2) and a 1µF ceramic capacitor
(Cfilt), the filter cut-off is approximately 16.9 Hz. This filter will capture the effect of most spikes, and will thus allow the
current accumulators to accurately reflect the total charge that has gone into or out of the battery.
