The BQ29413PWR is an integrated circuit (IC) component designed specifically for battery protection applications. It offers a comprehensive range of features to protect lithium-ion and lithium-polymer batteries from various potentially damaging conditions. Here are the key features of the BQ29413PWR:
1. Voltage Monitoring: The IC continuously monitors the individual cell voltages in battery packs and provides accurate voltage measurements. It allows overvoltage (OV) and undervoltage (UV) thresholds to be programmed for each cell, ensuring optimal usage and preventing cell damage.
2. Overcurrent Protection: The BQ29413PWR safeguards battery cells from excessive currents by monitoring the discharge and charge currents. It can be configured to detect overcurrent conditions and trigger the appropriate protection mechanism.
3. Short Circuit Protection: In case of a short circuit, the IC quickly detects the fault and disconnects the battery from the load, preventing further damage. It offers adjustable short circuit thresholds and response times to meet different application requirements.
4. Overtemperature Protection: The BQ29413PWR incorporates temperature sensing capabilities to monitor the battery pack's temperature. It activates protection measures if the temperature exceeds the programmed limits, preventing battery overheating and potential thermal runaway.
5. Cell Balancing: This IC supports cell balancing, which redistributes charge between the cells in a battery pack to equalize their voltages. The balancing operation helps enhance the overall performance, capacity, and lifespan of the battery pack
