2.7.4 Complete Example

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

Table 2-10 Example Settings
ADCIN Pin Desired Behavior ADCIN Decoded Value ADCIN Switch to Turn ON
ADCIN1 Minimum voltage: 5 V 0 1
ADCIN2 Maximum voltage: 20 V 4 5
ADCIN3

 Operating current: 3 A

Maximum current: 3 A

The ADCIN1 decoded value for a minimum voltage configuration of 5 V is 0. The ADCIN2 decoded value for a maximum value of 20 V is 4. The operating current and maximum current needs to be 3 A. 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 5 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 15 W, or a voltage inside the range of 5 V to 20 V (including 5 V and 20 V) cannot be provided. The plug flip LED lights up if the plug is inserted upside down.
