PRODUCTION DATA
USB Type-C and PD allows for voltages up to 20 V with currents up to 5 A. This introduces power levels that could damage components touching or hanging off of VBUS. Under normal conditions, all high power PD contracts should start at 5 V and then transition to a higher voltage. However, there some devices that are not compliant to the USB Type-C and Power Delivery standards and could have 20 V on VBUS. This could cause a 20-V hot plug that can ring above 30 V. Adequate design considerations are recommended below for these non-compliant devices.
