2.7.4 Complete Example

Find the appropriate ADCIN decoded values for ADCIN1, ADCIN2, ADCIN3, and ADCIN4 if the system is needed to accept 5V - 20V, and operate at 3A. The table below details the appropriate settings:

The ADCIN1 decoded value for a minimum voltage configuration of 5V is 0. The ADCIN2 decoded value for a maximum value of 20V is 7. The operating current and maximum current needs to be 3A. The combination of ADCIN3 and ADCIN4 decoded values to meet the required combination of operating current and maximum current is 3 and 1, respectively. Using the Switch to Decoded Table values, set the ADCIN1 switch 1 to on, the ADCIN2 switch 8 to on, the ADCIN3 switch 4 to on, and the ADCIN4 switch 2 to on. All other switches are in the OFF position.

Once the configuration is set, plug in the source by the USB-C connector. The PLUG_EVENT indicator LED lights up to indicate the cable is plugged in. The CAP_MIS indicator LED blinks continuously if the Capabilities Mismatch bit is set, which occurs when a source cannot provide a minimum power of 15W, or a voltage inside the range of 5V to 20V (including 5V and 20V) cannot be provided. The plug flip LED lights up if the plug is inserted upside down.
