1.1 Voltage and Current Requirements

Table 1-1 shows the USB Type-C PD charger specification. The PD controller negotiates a specific voltage depending on the input source. This input source is set to 5V at 3A, 9V at 3A, 15V at 3A, or 20V at 5A. Because of this variety of conditions, different profiles and charge current settings can be flashed based on the user scenario.
