Product Details

The MAX77958 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77958 Standalone USB Type-C and Power Delivery Controller.

The EV kit enables easy evaluation of the following features:

  • USB Type-C Detection/PD Communication (See Table 1 for Acronyms)
    • Power Role (Sink and Source), Data Role UFP and DFP) detection
    • PD Adapter Detection and PD Communication
    • Integrated VCONN Switch with OCP
    • Power/Data Role Swap
    • PPS (with PD Adapter Supporting PPS)
    • Audio and Debug Accessory Sink/Source Mode
    • Vendor Defined Message
  • BC1.2 Legacy Charger Detection: SDP, CDP, DCP and DCD Timeout
  • I2C Master to Control Companion IC
  • Nine Configurable GPIOs (GPIO6 for SID)

The EV kit contains a MAX77961 charger to demonstrate the I2C master feature of the MAX77958. The MAX77961 is a buck-boost charger for 2S/3S Li+ battery application and is capable of 3.5V to 25V input voltage, with a maximum programmable fast charging current of 6A. The MAX77961 can be configured as the 2-cell or 3-cell application by the CONG pin resistor (R5), refer to the MAX77961 data sheet for more details.

The MAX16904 (a buck converter) is installed on the EV kit to provide 5V to VCONN

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 the MAX77958. A Windows based software provides a user-friendly interface to exercise the features of the MAX77958.
