3 Description
The bq29209-Q1 device is a secondary overvoltage
protection IC for 2-series cell lithium-ion battery packs
that incorporates a high-accuracy precision
overvoltage detection circuit and automatic cell
imbalance correction.
The voltage of each cell in a 2-series cell battery
pack is compared to a factory programmed internal
reference voltage. If either cell reaches an
overvoltage condition, the OUT pin changes from low
to high state.
The bq29209-Q1 can perform automatic voltage-
based cell imbalance correction. Balancing can start
when the cell voltages are different by nominally
30 mV or more and stops when the difference is
nominally 0 mV. Cell balancing is enabled and
disabled by the CB_EN pin.
