PMIC - Battery Chargers
Application Field
BQ24005PWP is a versatile battery charger, perfect for applications where space for integration and thermal performance are key factors. It allows for efficient use of the available space, since it integrates the controller, MOSFETs and other key power components in a single package. Furthermore, it also provides up to 4A peak current and an excellent thermal performance, allowing the battery to reach an optimal charging level quickly.BQ24005PWP is the perfect Li-Ion/Li-Polymer battery charger for portable and stationary applications. It can support a wide range of Li-Ion/Li-Polymer chemistry and provides 4 selectable charging profiles, programmable input and charge current, and charge voltage/charge termination current to match a variety of devices. This versatile battery charger is also perfect for applications where space and thermal performance are important, as it integrates the controller, MOSFETs and other key power components in a single package.
Working Principle
BQ24005PWP is based on the synchronous boost topology, which allows for fast charging of the battery. The synchronous boost topology uses two power switches, one connected to the input voltage, and the other to the battery. The power switches are driven by the main PWM controller and operate in a quasi-continuous current mode to ensure proper charging of the battery. The PWM controller uses an internal voltage reference to determine the correct charging voltage for the battery and determines the correct current limit for the output stage. The current limit is then adjusted to provide the correct battery charging profile. Additionally, a variety of safety features are implemented to protect the battery and system such as thermal overload, overvoltage protection and reverse battery protection.BQ24005PWP is the perfect solution for portable and stationary applications, providing an effective and reliable charging solution to meet various application requirements. It allows incorporating the maximum available power while maintaining a safe and efficient charging profile.
