Description

The bq24308 is a highly integrated circuit designed to provide protection to Li-ion batteries from failures of the charging circuit. The IC continuously monitors the input voltage, the input current and the battery voltage. In case of an input over-voltage condition, the IC immediately removes power from the charging circuit by turning off an internal switch. In the case of an over-current condition, it limits the current to a safe value for a blanking duration before turning the switch off. Battery voltage may also be monitored and if the battery voltage exceeds the specified value the internal switch is turned off. Additionally, the IC also monitors its own die temperature and switches off if it becomes too hot.
