Texas Instruments  BQ298000RUGT

The BQ2980xy family of devices, featuring integrated charge-pump FET drivers, provideshigh-side primary battery cell protection for 1-series li-ion and Li-Polymer batteries, enablingconsistent Rdson across cell voltages. For better system thermal performance, the BQ2980 device’saccuracy 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 hostcontrol to create a system reset or shutdown function. Alternatively, the CTR pin can be configuredto connect an external Positive Temperature Coefficient (PTC) thermistor for FET OT protection inaddition to the internal die temperature sensor.
