    How Would You RoadTest the MAX77860: USB Type-C charger with integrated CC detection, Reverse Boost, and ADC

    rscasny

      I was forwarded some information on new device that features a switch mode charger with USB Type-C CC detection capability, reverse boost capability and a Safeout LDO. Called the MAX77860, it features a lot in just a  3.9mm x 4.0mm.  The charger features a single input, which works for both USB and high voltage adapters. It supports USB Type-C CC detection under BC 1.2 specification, and the power-path switch is integrated in the chip.

       

      The USB-OTG output provides true-load disconnect and is protected by an adjustable output current limit. It has an input current limit up to 4.0A and can charge a single-cell battery up to 3.15A. When configured in reverse-boost mode, the IC requires no additional inductors to power USB-OTG accessories. The on-chip ADC can help monitor the charging input voltage/current, battery voltage, charging/discharging current, and the battery temperature.

      Evaluation Board

      It has an evaluation kit called the MAX77860EVKIT. The MAX77860 evaluation system (EV system) is a fully assembled and tested surface-mount printed circuit board (PCB) that evaluates the single input switched-mode battery charger and other features.
