bq77207 Voltage & Temperature Protector Texas Instruments bq77207 Voltage and Temperature Protector provides a range of voltage and temperature monitoring. These include 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 or PTC thermistor, the device can detect overtemperature conditions.
