Temperature
The TS input of the bq2060 in conjunction with an NTC
thermistor measures the battery temperature as shown
in Figure 1. The bq2060 reports temperature in Tem-
perature().
THON may be used to connect the bias
source to the thermistor when the bq2060 samples the
TS input. THON is high impedance for 60ms when the
temperatureis measured, and driven low otherwise.
Gas Gauge Operation
General
The operational overview in Figure 2 illustrates the gas
gauge operation of the bq2060.
bq2060 registers.
Table 3 describes the
The bq2060 accumulates a measure of charge and dis-
charge currents and estimates self-discharge of the bat-
tery. The bq2060 compensates the charge current mea-
surement for temperature and state-of-charge of the
battery. The bq2060 also adjusts the self-discharge esti-
mation based on temperature.
The main counter RemainingCapacity() (RM) represents
the available capacity or energy in the battery at any
given time.
T he bq2060 adjusts R M for charge,
self-discharge, and leakage compensation factors.
