Introduction
The MAX77972 is an autonomous integrated FET charger with integrated fuel gauge, Universal Serial Bus (USB) Type- C and BC1.2 detection. The MAX77972 supports 4.5V to 13.7V inputs and up to 3.15A of charging current. Charge current and voltage are I2C and pin- configurable using resistors. The IC supports USB On- The- Go (OTG) reverse boost and includes a Smart Power SelectorTM (SPS), which is best for using limited adapter and battery power. The fuel gauge uses the ModelGaugeTM m5 algorithm, which provides industry- leading accuracy by combining the short- term accuracy and linearity of a coulomb counter with the long- term stability of a voltage- based fuel gauge. ModelGauge m5 automatically compensates for cell aging, temperature, and discharge rate and provides accurate state- of- charge (SOC) over a wide range of operating conditions. Charging is coordinated with the fuel gauge to provide 9- temperature- region JEITA charge control as well as step- charging. Other protection features include junction thermal regulation, over/under voltage protection, and short circuit protection. The USB Type- C Configuration Channel (CC) detection pins on the MAX77972 enable automatic USB Type- C power source detection and input current limit configuration. To support a variety of legacy USB types as well as proprietary adapters, the IC also integrates BC1.2 detection using the D+ and D- pins. The IC runs the CC pin and BC1.2 detection automatically as soon as a USB plug is inserted without any software control. The IC is available in a lead- free 3.208mmx3.258mm 36- bump 0.5mm pitch Wafer- level packaging (WLP) package.
