Analog Devices / Maxim Integrated MAX77757 Evaluation Kit

Analog Devices Inc. MAX77757 Evaluation Kit is a fully assembled and tested Printed Circuit Board (PCB). The MAX77757 kit is designed to evaluate MAX77757 IC a standalone 3.15A USB Type-C® autonomous charger with JEITA. The MAX77757 IC can operate from 4.5V to 13.7V input, with a fast-charge current up to 3.15A, and a maximum input current limit of 3A. The MAX77757 evaluation kit features USB Type-C CC detection, battery charging compliant with the USB battery charging specification, and proprietary adapter detection upon input insertion. This kit exhibits the automatic configuration of the charger input current limit to the maximum allowable current from the input source. The MAX77757 evaluation kit includes the variable resistor and thermistor to demonstrate the JEITA compliance.
