MAX77787JEVKIT#

MAX77787 evaluation kit is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77787, standalone 3.15A USB Type-C® autonomous charger with JEITA. The MAX77787 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 MAX77787 is offered to support Li-ion batteries with JEITA compliance. It also has another option that supports LiFePO4 batteries with non-JEITA compliance. 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 MAX77787 has the reverse-boost capability, which is enabled by the ENBST pin to allow the 5.1V/1.5A output to CHGIN. The EV kit includes the variable resistor and thermistor to demonstrate the JEITA compliance.
