3 Description
The BQ77216 family of products provides a range
of voltage and temperature monitoring including
overvoltage (OVP), undervoltage (UVP), open wire
(OW), and overtemperature (OT) protection for Liion
battery pack systems. Each cell is monitored
independently for overvoltage, undervoltage, and
open-wire conditions. With the addition of an
external NTC thermistor, the device can detect
overtemperature conditions.
In the BQ77216 device, an internal delay timer
is initiated upon detection of an overvoltage,
undervoltage, open-wire, or overtemperature
condition. Upon expiration of the delay timer, the
respective output is triggered into its active state
(either high or low, depending on the configuration).
