Description
General part information
BQ298215 Series
The BQ298xx 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 BQ298xx device’s accuracy enables the use of a sense resistor as low as 1mΩ.
The CTR pin in the BQ298xx 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 BQ2980xx devices support zero-volt (0V) charging, while the BQ2982xx devices have this disabled.
