The IC component BQ29413PW is a highly integrated, precision voltage supervisor and protector designed specifically for lithium-ion and lithium-polymer batteries. It offers a range of features and functions to ensure the safety and optimal performance of battery packs.
One of the key features of the BQ29413PW is its precise voltage monitoring capability. It can monitor up to four individual cell voltages or a combination of voltages, making it suitable for various battery pack configurations. With a programmable overvoltage detection threshold, it can accurately detect and prevent overcharging of the cells.
This IC component also provides accurate undervoltage detection, helping to protect the battery pack from deep discharge situations. It can independently monitor each cell voltage and enable timely warnings or actions to prevent damage to the cells.
Moreover, the BQ29413PW offers a robust protection mechanism against overcurrent conditions. It includes short-circuit protection by disabling the discharge FETs, preventing excessive current flow. The overcurrent detection threshold is programmable, allowing customization according to the specific requirements of the battery pack.
To ensure safe and reliable operation, this IC component features a built-in charge safety timer. It can detect and terminate the charging process if it exceeds a predefined period, guarding against potential hazards associated with prolonged charging.
The BQ29413PW IC also provides a fault flag output, allowing the system to quickly identify and respond to any abnormal conditions. This feature aids in troubleshooting and timely maintenance of battery packs
