Note 1: This table details the power consumption of the UPD301B/C device as measured during various modes

of operation for a single port Source-Only implementation (i.e.: loading a PSF Source-only configuration

and programming with default settings). The power consumption may vary significantly depending on the

utilization SAMD20 MCU to handle any additional custom system-specific functions. Refer to the respec-

tive SAMD20E and UPD350 datasheets for more details on the power consumption of these two devices

under certain specific usage scenarios. Also refer to Section 4.2, "Power States" for additional information.

Power dissipation is determined by temperature, supply voltage, and external source/sink requirements.

Maximum values represent very short bursts of activity over a small amount of time. Typical values repre-

sent averaged current consumption over time.

2: STANDBY is equivalent to USB Type-C™ specification’s Unattached.SRC

3: Currents measured with all 3.3V rails tied together.
