Power Consumption

This section details the power consumption of the device as measured during various modes of operation. Power dis-

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

HS Current

Example Active Data Transfer Current Calculation: 2 SS Ports and 2 HS Ports

Active Data Transfer Current (mA @ 3.3V)

49mA + (NSS_PORTS * 6mA) + (NHS_PORTS * 4mA)

49mA + {2 * 6mA} + {2 * 4mA} = 69mA

Active Data Transfer Current (mA @ 1.2V) 239mA + (NSS_PORTS * 125mA) + (NHS_PORTS * 1mA)

239mA + {2 * 125mA} + {2 * 1mA} = 491mA

Note:

Actual Power Consumption measurements are highly dependent on the USB host’s ability to utilize the full

bandwidth of USB2 and USB3 channels. In actual in-system measurements, significant variation in power

consumption measurement from host to host and data transfer type is expected.

Note:

In the Active Idle and Active Data Transfer sections of the Device Power Consumption table, the various

port configurations are indicated via the following acronyms:

SS = USB 3.2 SuperSpeed (Gen 1)

HS = USB 2.0 High Speed
