The BQ24400PWRG4 is a PMIC - Battery Chargers device that is used to manage and read battery power in order to monitor and control the power usage of the device. It is designed to provide power management and read central battery current in order to offer the power necessary for the standby, sleep, and active operating states of the device.

The BQ24400PWRG4 offers a wide range of features which include low-side current sensing, adjustable charging current and regulation, output voltage adjustment, adjustable input current regulation, LED indicator drive, programmable watchdog timer, and over-temperature protection. It has a 5V input voltage, an operating temperature range of -40°C to 85°C, and a low-side current sensing of up to 4A and up to 300mA.

The device is typically used in applications requiring the optimization of the battery\'s charge and discharge from the device in order to extend the energy consumption throughout the device\'s life. It also offers advantages in mobile and handheld applications, where the device needs to be charged in different environment conditions, as well as in embedded systems.

The main working principle of the BQ24400PWRG4 is its internal field effect transistor. This device is connected to the input voltage source, and is used to regulate the charging current. The current is regulated based on different variables, such as the input voltage, the battery’s charge, and the temperature. When the current exceeds the maximum set value, the thyristors or mosfets switch to a higher resistance in order to reduce the current.

When a new battery is connected to the device, the device can detect the battery’s charge and set the charge current accordingly. In addition to this, the device also monitors the cell’s temperature in order to safely charge the battery. Once the battery is fully charged, the device will switch to a trickle charge mode to maintain the battery’s capacity. The BQ24400PWRG4 also offers protections against overcharging, high temperatures, and external short circuits.
