ADC

The FUSB15201 allows for up to 12 signals to be

measured and converted using the internal 10−bit ADC.

For most applications, this will consist of two VBUS

voltages, two NTC temperature channels, two D+/D− BC1.2

and, optionally, two CC1/2 ports. The table below shows

the typical FUSB15201 configuration along with the

expected settings for the ADC module.
