It supports over-voltage protection, heat dissipation and charge protection for the safety of Li-ion/Li-polymer batteries. This PMIC also supports active discharge, with a discharge rate of up to 15A.

Application Field of BQ29312PW

BQ29312PW is ideal for use in mobile HD devices, such as digital cameras, PDAs and smartphones. It is designed to provide advanced features such as over-voltage protection, thermal protection and charge protection for Li-Ion/Li-Polymer batteries. It is also suitable for ultra-slim devices, because of its low profile design. Furthermore, it supports active discharge, with a discharge rate of up to 15A.

Working principle of BQ29312PW

The BQ29312PW is an advanced PMIC specifically designed for Li-ion/Li-polymer battery management. It monitors the battery voltage and provides protection by detecting the onset of over-voltage conditions in the battery. In case of an over-voltage condition, it will immediately shut down the system but still maintain a “safe” voltage level, preventing any further damage to the battery. In addition, it can detect thermal conditions in the battery and provide thermal protection. Moreover, it supports active discharge, with a discharge rate of up to 15A.

The BQ29312PW features advanced features such as Hot Plug Detection and Automatic Reset. Hot Plug Detection allows the controller to detect when a battery is connected to the system and adjust the voltage accordingly. The Automatic Reset feature detects any fault conditions, such as a short circuit or over-current, and automatically resets the system. With these advanced features, the BQ29312PW ensures maximum protection for Li-ion/Li-polymer batteries.

In summary, the BQ29312PW is an advanced PMIC designed for Li-ion/Li-polymer battery management. It features over-voltage protection, thermal protection, charge protection and active discharge, ensuring maximum protection for the battery. Additionally, its advanced features such as Hot Plug Detection and Automatic Reset maximize safety and reliability. This PMIC is ideal for use in mobile HD and ultra-slim devices.
