MAX77789 3.15A Charger Integrated Circuit (IC) Analog Devices / Maxim Integrated MAX77789 3.15A Charger Integrated Circuit (IC) offers integrated USB Type-C® CC detection and reverse boost capability. MAX77789 operates within a -40°C to +85°C temperature range and a 4.6V to 13.4V input voltage range with a 3A maximum input current limit. The IC implements the adaptive input current limit (AICL) function (regulates the input voltage by reducing the input current) to prevent the voltage of a weak adapter from collapsing or folding back.
