Figure 27. Schematic Example for USB 2.0, MHL, and UART Combination; NCN1188 Being Supplied by Protected
VBUS 5 V
In this second design proposal, as NCN1188 must be
active only when VBUS accessories are connected (USB
cable, UART cable and MHL cable), the device is supplied
from a protected VBUS 5 V. This design arrangement limits
the system’s overall quiescent current and saves battery life.
Figure 27 also pictures NCN1188 around a USB 3.0
MicroB topology: USB 2.0, UART and MHL Video pairs
remain multiplexed with D and D+ while the two USB 3.0
differential pairs are directly connected to the main
communication processor.
The flexibility of the NCN1188 offers many extra
application and design combinations.
