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.
