BQ298000RUGT Description

Short technical summary and product information.

The Texas Instruments BQ298000RUGT is an active high-side protector IC specifically designed for single-cell lithium-ion and lithium-polymer batteries. It provides essential safety features including overvoltage, undervoltage, overcurrent (during charge and discharge), short-circuit discharge, and overtemperature protection.

 

This device operates with a maximum input voltage of 5.5V and features precise voltage protection with tolerances of ±10mV for overvoltage and ±20mV for undervoltage. Current protection tolerances are ±1mV for overcurrent in charge and discharge, and ±5mV for short-circuit discharge. The operating temperature range is -40°C to 85°C.

 

The BQ298000RUGT supports a low sense resistor value down to 1mΩ and includes a high-side FET drive. It also features 0V charging capability and a CTR pin for FET override control, useful for system reset or shutdown functions. The IC is housed in an 8-X2QFN package measuring 1.5mm x 1.5mm.

 

With typical operating current consumption of 5µA in normal mode and a low shutdown mode consumption of 0.1µA maximum, the BQ298000RUGT is suitable for power-sensitive battery management applications.
