The BQ29718DSER is an integrated circuit (IC) component that offers a comprehensive solution for battery pack protection against overcharge, over-discharge, and overcurrent conditions. This IC is specifically designed for use with lithium-ion and lithium-polymer battery packs. Here are some key features and an overview of the BQ29718DSER:
1. Overvoltage Protection: The BQ29718DSER ensures the battery pack remains within the safe operating voltage range by providing overvoltage protection. It immediately detects and disconnects the battery pack from the charging source when the voltage exceeds the predefined threshold.
2. Undervoltage Protection: This IC also incorporates undervoltage protection, which prevents the battery pack from being discharged beyond safe limits. When the voltage drops below a certain threshold, the BQ29718DSER disconnects the battery pack from the load, preventing damage to the cells.
3. Overcurrent Protection: The BQ29718DSER offers robust overcurrent protection, safeguarding the battery pack against excessive current flow. In case of a short circuit or high discharge rates, it quickly interrupts the circuit, preventing any potential harm to the cells or connected devices.
4. Balancing and Cell Monitoring: This IC component supports passive cell balancing, which ensures that cells in the battery pack are evenly charged and discharged. It also includes an integrated cell monitoring feature that provides accurate voltage measurements for individual cells, enabling accurate state-of-charge estimations
