Maxim Integrated MAX77751 3.15A USB-C Autonomous Charger is a 3.15A charger with integrated USB Type-C® CC detection and reverse boost capability. Easily configure the fast-charge current and top-off current thresholds with resistors. The MAX77751 operates with an input voltage of 4.5V to 13.7V. It has a maximum input current limit of 3A. The IC also implements the adaptive input current limit (AICL) function. This regulates input voltage by reducing input current to prevent the voltage of a weak adapter from collapsing or folding back.
