The BQ24266RGER is an integrated circuit (IC) component developed by Texas Instruments. It is a highly integrated, single-cell Li-ion battery charger and system power path management device. The IC is designed to provide a comprehensive solution for applications that require battery charging and system power management in a single device.
Key features of the BQ24266RGER include:
1. High-efficiency Charging: The IC integrates a synchronous buck converter and supports up to 2 A of charging current. Its high-efficiency power path management allows simultaneous charging of the battery and powering the system.
2. Battery Safety: The IC includes various safety features such as thermal regulation to prevent overheating, thermal shutdown to protect against excessive temperature, and battery temperature monitoring to ensure safe charging.
3. Charging Modes: The BQ24266RGER offers different charging modes to optimize the battery charging process. It supports constant-current constant-voltage (CCCV) charging and provides programmable charge current and termination current options.
4. USB OTG: The IC incorporates a USB On-The-Go (OTG) feature, enabling the device to act as a power source to charge external devices or act as a peripheral device drawing power from the USB port.
5. Input Power Path Management: The IC features an integrated power path selector with reverse leakage protection. It automatically switches between input power sources, such as a USB port or an adapter, to power the system or charge the battery
