The bq2980xy family of devices, featuring integrated charge-pump FET drivers, provides
high-side primary battery cell protection for 1-series Li-Ion and Li-Polymer batteries, enabling
consistent Rdson across cell voltages. For better system thermal performance, the bq2980 devices
accuracy enables the use of a sense resistor as low as 1 mΩ.
The CTR pin in the bq2980 device can be configured to override the FET driver by host
control to create a system reset or shutdown function. Alternatively, the CTR pin can be configured
to connect an external Positive Temperature Coefficient (PTC) thermistor for FET OT protection in
addition to the internal die temperature sensor.
