Description

The MAX77975/MAX77976 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77975/MAX77976 single-cell lithium-ion battery charger.

The MAX77975/MAX77976 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/MAX77976 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/MAX77976 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 the slave I2C port on MAX77975/MAX77976. Windows®- based graphical user interface (GUI) software provides a user-friendly interface to exercise the features of the MAX77975/MAX77976.
