产品详情

The MAX77785/MAX77786 evaluation kits (EV kit) are fully assembled and tested printed circuit boards (PCB) that demonstrate the MAX77785/MAX77786 single-cell lithium-ion battery chargers.

The MAX77785/MAX77786 are for 1S Li+ battery applications and can operate with a 4.7V to 18.2V input voltage with a maximum charging current up to 3.5A/5.5A. The MAX77785/MAX77786 ICs offer a reverse boost as well as fully integrated low-power loss switches to provide small solution size and high efficiency. The EV kits demonstrate the performance of the MAX77785/MAX77786 charger and provide the convenience of evaluating full USB Type-C^® power-delivery (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 on-the-go (OTG) mode.

A Micro-B USB cable is included in the EV kit to serve as the interface from a USB port on a Windows^® PC to the subordinate I2C port on the MAX77785/MAX77786.
