Evaluates: MAX77751

MAX77751 Evaluation Kit

General Description

The MAX77751 evaluation kit (EV kit) is a fully assembled

and tested printed circuit board (PCB) that demonstrates

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, bat-

tery charging compliant with the USB Battery Charging

Specification Revision 1.2 (BC1.2), proprietary adapter

detection upon input insertion, and automatic configura-

tion 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.
