Charge current and cell chemistry fit
The chip also integrates over-temperature and over-voltage fault protection, so you can skip external protection FETs in most designs.
I²C programmability and system integration
The I²C interface lets the host microcontroller adjust charge current, termination voltage, and input current limit in real time — useful for systems that share the USB bus with other loads. The supply voltage range goes up to 10 V, covering standard 5 V USB and 9 V fast-charge adapters without an external buck-boost.
Temperature grade and package constraints
Texas Instruments lists the base number BQ24160 — the RGET suffix denotes the reel and package variant.
