MAX77986AEVKIT#

MAX77986AEVKIT# evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77986A single-cell lithium-ion battery charger. The MAX77986A is for 1S Li+ battery applications and can operate with a 4.7V to 19V input voltage with a maximum charging current of 5.5A. The IC offers a reverse boost as well as fully integrated low power loss switches to provide a small solution size and high efficiency. The EV kit demonstrates the performance of the IC and provides the convenience of evaluating full USB Type-C® PD solutions with 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 server I2C port on the IC. Windows®-based GUI software provides a user-friendly interface to exercise the features of the IC.
