A common and highly recommended choice for a charger and safety control IC for Lithium-ion batteries is the Texas Instrument's BQ24195 IC.
Here are some of its most appealing features:
It is a standalone switch-mode battery charger that supports charging plus a boost regulator for portable charging.
It supports a wide range of input sources, including standard USB host ports and adjustable high-power wall adapters.
It provides a complete charging and power solution as it supports up to 2.5 A of charging current as well as provides system power up to 20 V/2 A.
Alternatively, if your design task requires a Battery Management System (BMS) for more sophisticated battery control and safety, including cell balancing, temperature protection, and precise SOC (State Of Charge) computation, you might want to look at ICs like the LTC6811 from Analog Devices (Linear Technology).
Remember to thoroughly read the datasheet of the IC to ensure it fits your specific needs. Since different ICs will have varying feature sets, the best IC for you depends on your specific requirements for your project.
