SLUSAS0D – DECEMBER 2011 – REVISED APRIL 2017 bq2946xx Single-Cell Protector for Li-Ion Batteries
1 Features 3 Description The bq2946xx family of products is a secondary-level
overvoltage monitor and protector for Li-Ion battery
pack systems. The cell is monitored for overvoltage
condition and triggers an internal counter once the
OVP threshold is exceeded; after a fixed set delay,
the out is transitioned to a high level. The output is
reset (goes low) if the cell voltage drops below the
set threshold minus the hysteresis. 1 Single-Cell Overvoltage Monitor for Secondary
