The BQ24074RGTRG4 is a PMIC (Power Management Integrated Circuit) that is used as a battery charger. It is intended for use in applications such as mobile phones, tablet computing, remote controls, and other low power applications.

The BQ24074RGTRG4 works with an external voltage source to provide a regulated charging current to a battery. The power source can be either a wall supply or a USB port that provides 5 volts or higher voltage.

The BQ24074RGTRG4 offers features such as overvoltage protection and a thermal shutdown that prevent damage to the battery. The circuit also integrates an input power path controller with an I2C interface that allows data communication with the charging source. In addition, the device offers an adjustable charge current limit, and automatic switching between charging sources.

The BQ24074RGTRG4 is a highly integrated charging solution. It includes an integrated PowerPath controller and a low-loss switch. The PowerPath controller manages the input power by minimizing the power dissipation and increasing efficiency. It also supports I2C communications to enable more accurate tracking of charge state and battery health.

The low-loss switch is used to switch between different power sources. It can switch between a wall supply, a USB port, or a secondary power source such as a solar panel. The switch includes accurate current-limiting and overvoltage protection to prevent damage to the battery.

The BQ24074MGRG4 is a robust, low power charger for single cell Li-ion batteries. It offers features like overvoltage protection, thermal shutdown, and adjustable charge current limit. Its integrated PowerPath controller and low-loss switch make it an ideal choice for low power applications such as mobile phones, remote controls, and other portable devices.
