BQ2980, BQ2982  
SLUSCS3H – OCTOBER 2017 – REVISED JULY 2021  
BQ298xyz Voltage, Current, Temperature Protectors with an Integrated High-Side  
NFET Driver for Fast/Flash Charging Single-Cell Li-Ion and Li-Polymer Batteries  
1 Features  
3 Description  
•
Voltage protection:  
The BQ298xyz 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 BQ298x device's accuracy enables the use of a  
sense resistor as low as 1 mΩ.  
– Overvoltage (OV): ±10 mV  
– Undervoltage (UV): ±20 mV  
Current protection  
– Overcurrent in charge (OCC): ±1 mV  
– Overcurrent in discharge (OCD): ±1 mV  
– Short circuit in discharge (SCD): ±5 mV  
Temperature protection:  
– Overtemperature (OT)  
Additional features:  
– Supports as low as a 1-mΩ sense resistor

The CTR pin in the BQ298x 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. The BQ2980xy devices support  
zero-volt (0-V) charging, while the BQ2982xy devices  
have this disabled.  
(RSNS  
)
– High-side protection  
– High Vgs FET drive  
– 0-V charging (only BQ2980)  
– CTR pin for FET override control for system  
reset/shutdown  
– Configure CTR for second OT protection  
through an external PTC thermistor  
Current consumption:  
– NORMAL mode: 4 µA  
– SHUTDOWN mode: 0.1-µA maximum
