Description
General part information
BQ77216 Series
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 Li-ion 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).
