MAX77975EVKIT

$150.00

説明

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.

説明

The MAX77975/MAX77976 is a high-performance high-input 3.5/5.5A fast charger with Smart Power Selector^TM. The IC can operate as a reverse boost without an additional inductor, allowing the battery to share its power through the charging port and is voltage programmable from 5V to 12V. The device features fully integrated low-loss power switches to provide small solution size and high-efficiency, even at high input voltage and high charging current. Its high switching frequency allows the use of a smaller sized inductor. The IC features true load disconnection in reverse boost mode and has an adjustable output current protection limit. The device is highly flexible and programmable through I²C configuration.

The battery charger includes a Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start-up gracefully as soon as an input source is available, even when the battery is deeply discharged (dead battery) or missing. It can be configured so that when power is applied to the charger input, the battery charging can automatically start.
