Product Overview

MAX77975 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77975 single-cell lithium-ion battery charger. The MAX77975 is for 1S Li+ battery applications and can operate with a 3.8V to 19V input voltage with a maximum charging current of 3.5/5.5A. The MAX77975 offers a reverse boost as well as fully integrated low power loss switches to provide small solution size and high efficiency. The EV kit demonstrates the performance of the MAX77975 charger and provides the convenience of evaluating full USB Type-C® PD solutions with the MAX77958 USB Type-C PD controller. This combination allows fast charging of the battery through the USB Type-C port as well as reverse powering the USB Type-C port with battery OTG mode. A Micro-B USB cable is included in the package to serve as the interface from a USB port on a Windows PC to I2C port on MAX77975.
