How about the lithium battery charge management chip HL7016?

The HL7016 is the first 12V high-voltage input fully integrated switch mode charger in China, which realizes high input voltage and USBOTG boost mode and I2C interface programmable. The chip has built-in voltage, current, temperature and other detection and protection functions. The voltage and current parameters are set and adjusted through the I2C interface to ensure the safety of lithium battery charging. In addition, the chip also has a built-in battery activation function to solve the system crash caused by battery short circuit. Compared with the traditional charging method, the HL7016 reduces the charging time by more than half.

The HL7016 also integrates the USBOTG5V boost output function. When enabled, it can boost the battery voltage to 5.0V output and provide a maximum output current of up to 2.1A, making it ideal for applications such as smart phones, tablets and mobile power supplies.
