Analog Devices / Maxim Integrated MAX77958EVKIT-3S6 Evaluation Kit

Analog Devices Inc. MAX77958EVKIT-3S6 Evaluation Kit provides a reference design for a 3 cell (3S) Li-Ion battery charging circuit based on the MAX77958 USB Type-C and USB PD Controller and the MAX77961 USB-C Buck-Boost Charger. The MAX77958 is a robust solution for USB Type-C CC detection and Power Delivery (PD) protocol implementation. The MAX77958 detects connected accessories or devices by using Type-C CC detection and USB PD messaging. The MAX77961 is a high-performance, wide-input 6A Buck-Boost Charger with Smart Power Selector™. The MAX77958EVKIT-3S6 also includes a MAX16904 Buck Converter to provide 5V to the VCONN pin.

ADI MAX77958EVKIT-3S6 Evaluation Kit can be connected to a Windows® PC via a USB cable. A Windows-based Graphic User Interface (GUI) software provides a quick, easy, and thorough evaluation of the features of the MAX77958.
