Table 11. Power specifications
Condition Specification
Bus-powered, USB 5 V supply
Suspend mode <2.5 mA
Enumeration <100 mA
Run mode <500 mA
Run mode 1.05 W max (210 mA input current)
Run mode 1.45 W max
The total power consumption for all external loads must be less than this
value, and each load must meet the individual specification for the
terminal.
Power per output = Iout × 5 V
(for example, @ 24 mA, P = 0.024 × 5 = 120 mW / output)
Power (W) = Iout × 5 V
Run mode 4.25 V min, 5.25 V max
Suspend mode, 0 V
enumeration
Run mode, no 290 mA max (1.45 W)
