open-in-new Find other Battery protectors


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.

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.
