Functional Description
General Operation
The bq2092 determines battery capacity by monitoring
the amount of charge input to or removed from a
rechargeable battery. The bq2092 measures discharge
and charge currents, estimates self-discharge, and
monitors the battery for low-battery voltage thresh-
olds. The charge measurement is made by monitoring
the voltage across a small-value series sense resistor
between the battery's negative terminal and ground.
The available battery charge is determined by moni-
toring this voltage over time and correcting the meas-
urement for the environmental and operating condi-
tions.
Figure 1 shows a typical battery pack application of the
bq2092 using the LED capacity display, the serial port,
and an external EEPROM for battery pack program-
ming information. The bq2092 must be configured and
calibrated for the battery-specific information to ensure
proper operation. Table 1 outlines the externally
programmable functions available in the bq2092. Refer
to the Programming the bq2092 section for further
details.
An internal temperature sensor eliminates the need
for an external thermistor—reducing cost and compo-
nents.
An internal, temperature-compensated time-
base eliminates the need for an external resonator,
further reducing cost and components.
