This application note provides an overview of the BQ20Z70PW-V150 and its features, working principle and applications.

The BQ20Z70PW-V150 is a Fuel Gauge IC (integrated circuit) specifically designed for charging and managing a variety of chemistries, including lithium ion and lithium ion battery packs. It has a built-in full-bridge Power Path (PP) controller to ensure that power is routed safely and efficiently between the power sources and the battery. The device is also equipped with built-in safety features to protect the battery and the system from potential threats. It has a dedicated charge state machine with internal timing capability, which provides precise control over the charging process and improves the overall efficiency of the system.

The working principle of the BQ20Z70PW-V150 starts when the voltage of the battery pack is detected then based on the settings applied by user, the device can control the state of the system and control if charging is required. If charging is required, the device will calculate the end-point voltage and apply a programmed current to the battery pack. The device supports both slow and fast charging modes and will alert the user when a safe charging level is reached. To monitor the progress of the charging and the state of the battery, the device will continuously measure the battery voltage, temperature and current. The device will then compare the readings with programmed parameters stored in internal memory, and display the information on the device displays or transmit the information over the I2C protocol.
