BQ29700DSER General Description
The BQ29700DSER is a battery protection integrated circuit (IC) developed by Texas Instruments. This IC is designed to provide overcharge and overdischarge protection for single-cell Li-ion or Li-polymer batteries. It features a precision voltage detection circuit that monitors the cell voltage and disconnects the battery from the load when the voltage exceeds the safe threshold. The BQ29700DSER also includes a built-in timer that prevents overcharging and overdischarging, ensuring the battery remains within safe operating limits. Additionally, it has a low quiescent current in standby mode, which helps to conserve energy and extend battery life. This IC is housed in a small, space-saving package and offers high accuracy and reliability in protecting batteries from damage due to overcharging or overdischarging. It is suitable for a wide range of portable devices, such as smartphones, tablets, and laptops, where battery safety is a top priority
