MAX77757 3.15 A USB Type-C® Autonomous Charger with JEITA
Analog Devices' charger is designed for 1-cell Li-Ion/LiFePO4 batteries and applications such as power banks
Analog Devices' MAX77757 is a standalone 3.15 A charger with integrated USB Type-C CC detection with JEITA compliance that supports reverse boost capability. The fast-charge current is easily configured with resistors. The MAX77757 operates with an input voltage of 4.5 V to 13.7 V and has a maximum input current limit of 3 A. The IC implements the adaptive input current limit (AICL) function that regulates the input voltage by reducing input current to prevent the voltage of a weak adapter from collapsing or folding back.
