The bq2980 device provides a
primary battery cell protection for 1 s battery pack by open CHG or DSG FETs at fault conditions.
The device family provides a wide range of overvoltage and undervoltage threshold range, covering
various li-ion chemistries. The bq2980 device monitors across an external sense resistor
for current protection. The device family has an internal temperature sensor to provide overtemperature
The CTR pin in bq2980 can be configured to override the FET driver by host control,
suitable to create a system reset or shutdown function. Alternatively, the CTR pin can be
configured to connect an external PTC for FET overtemperature protection in addition to the
internal die temperature sensor.
