Hi-Speed USB OTG controller
11. Power consumption
Remark:
The idle operating current (I
CC
), that is, when the ISP1761 is in operational
mode—initialized and without any devices connected, is 70 mA. The additional current
consumption on I
CC
is below 1 mA per port in the case of full-speed and low-speed
devices.
Remark:
Deep-sleep suspend mode ensures the lowest power consumption when V
CC
is
always supplied to the ISP1761. In this case, the suspend current (I
CC(susp)
) is typically
about 150
μ
A at room temperature. The suspend current may increase if the ambient
temperature increases. For details, see
Section 7.6
.
Remark:
In hybrid mode, when V
CC
is disconnected I
CC(I/O)
will be generally below
100
μ
A. The average value is 60
μ
A to 70
μ
A.
