The MAX77751 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77751, the standalone 3.15A USB Type-C® autonomous charger.
The EV kit is a switch-mode charger and Smart Power Selector™ with autonomous configuration. The MAX77751 can operate from 4.5V to 14V input, with the fast-charge current up to 3.15A and maximum input current limit of 3A.
The EV kit features USB Type-C CC detection, battery charging compliant with the USB Battery Charging Specification Revision 1.2 (BC1.2), proprietary adapter detection upon input insertion, and automatic configuration of the charger input current limit to the maximum allowable current from the input source.
The MAX77751 has the reverse-boost capability, which is enabled by the ENBST pin to allow the 5.1V/1.5A output to CHGIN.
