DESCRIPTION
The bq2084-V150 SBS-compliant gas gauge IC for
battery pack or in-system installation maintains an
accurate record of available charge in Li-ion or
Li-polymer batteries. The bq2084-V150 monitors
capacity and other critical parameters of the battery
pack and reports the information to the system host
controller over a serial communication bus. It is
designed to work with the bq29312A AFE protection
IC to maximize functionality and safety and minimize
component count and cost in smart battery circuits.
Using information from the bq2084-V150, the host
controller can manage remaining battery power to
extend the system run time as much as possible.
The bq2084-V150 uses an integrating converter with
continuous sampling for the measurement of battery charge and discharge currents. Optimized for
coulomb counting in portable applications, the
self-calibrating integrating converter has a resolution
better than 0.65-nVh and an offset measurement
error of less than 1-μV (typical). For voltage and
temperature reporting, the bq2084-V150 uses a
16-bit A-to-D converter. With the bq29312A, the onboard ADC also monitors the pack and individual
cell voltages in a battery pack and allows the
bq2084-V150 to generate the control signals
necessary to implement the cell balancing and the
required safety protection for Li-ion and Li-polymer
battery chemistries.
The bq2084-V150 supports the Smart Battery Data
(SBData) commands and charge-control functions. It
communicates data using the System Management
Bus (SMBus) 2-wire protocol. The data available
include the battery's remaining capacity,
temperature, voltage, current, and remaining
run-time predictions.
The bq2084-V150 provides LED drivers and a
pushbutton input to depict remaining battery capacity
from full to empty in 20%, 25%, or 33% increments
with a 3-, 4-, or 5-segment display.
