The power delivery system works as follows:
1. If the power delivery system detects a non Type-C power adapter (legacy USB), EZ-PD™ CCG3 will charge the
battery at 100 mA. EZ-PD™ CCG3 will also disable the consumer and provider paths.
2. On detection of a Type-C power adapter, EZ-PD™ CCG3 will request 5 V at 3 A, 9 V at 3 A, or 12 V at 3 A depending
on the host capability. After the power level is successfully negotiated, the consumer path is enabled by
turning ON the load switch U13. This load switch is hardware-limited to supply up to 1 A through header J16
to an external device. CCG3 will use the remaining current to charge the battery connected to J15 at a higher
charging rate up to 1.5 A and PD output voltage availability indicator (LED7) will be turned ON.
3. EZ-PD™ CCG3 will also advertise that it can provide 5 V, 9 V, or 12 V if a DC power supply capable of providing
either of these voltages is connected at VIN (J9). The current is limited in this case to 1 A. Note that the external
supply must be capable of providing this current. If a connected, Type-C device requests power, the provider
path is enabled by turning on load switch U31.
