The BQ298009RUGR from Texas Instruments is an integrated circuit designed for high-side primary battery cell protection in single-cell Li-ion and Li-polymer battery applications. It features robust protection mechanisms including overvoltage (OV) with ±10mV accuracy and undervoltage (UV) with ±20mV accuracy.
Current protection is provided for overcurrent in charge (OCC) and discharge (OCD) with ±1mV accuracy, and short circuit in discharge (SCD) with ±5mV accuracy. The device also includes overtemperature (OT) protection. It supports a low sense resistor value down to 1mΩ for improved thermal performance.
This device operates within a temperature range of -40°C to 85°C and is housed in an 8-pin X2QFN package measuring 1.50mm x 1.50mm. It consumes a typical 4µA in normal mode and a maximum of 0.1µA in shutdown mode. The BQ2980xy devices, including this one, support 0-V charging.
Applications for the BQ298009RUGR include smartphones, tablets, power banks, and wearables, where reliable battery protection is critical for safety and performance.
