CW6116 is a highly-integrated 3A switched-mode Li-Ion and Li-polymer battery charger with power path management. Its ultra-low impedance on power path helps improve charging efficiency, reduce charging time and extend battery life during discharge. The charging efficiency at 5V/2A is 92%. CW6116 supports USB-OTG with up to 1.5A supply current. Charging and system settings could be flexible configured via the I2C interface. Its compact QFN 4mmx4mm package, combing with using 1uH small profile inductor, makes it a good selection for fast charging application.
