Product Details

The MAX77884/MAX77885 evaluation kits (EV kits) are fully assembled and tested printed circuit boards (PCBs) that demonstrate the operation of the MAX77884/MAX77885 single-cell lithium-ion battery chargers.

The MAX77884/MAX77885 support 1S Li+ battery applications and operate with an input voltage range of 4.4V to 21V. The MAX77884 supports a maximum charging current of 3.5A, while the MAX77885 supports up to 5.5A. Both ICs integrate reverse boost functionality and low-power-loss switches, enabling a compact solution footprint and high efficiency.

The EV kits validate the performance of the MAX77884/MAX77885 chargers and enable evaluation of complete USB Type-C® power delivery (PD) solutions using the MAX77958 USB Type-C PD controller. This configuration supports fast battery charging through the USB Type-C port and reverse power delivery to the USB Type-C port in battery on-the-go (OTG) mode.

A Micro-B USB cable is included to establish communication between a Windows® PC and the subordinate I2C port on the MAX77884/MAX77885. A Windows-based graphical user interface (GUI) for interacting with the EV kits is available for download from the Analog Devices website at www.analog.com. The software operates on Windows 7 and newer versions.
