A simplified functional block diagram of
ISOUSB211-Q1 is shown in
Figure 7-1. The device comprises the following:
- Transmit and receive circuits and pull-up and pull-down resistors according to the USB standard.
- Digital logic to handle bi-directional communication, and various state-transitions.
- Internal LDOs to generate V3P3Vxand V1P8Vxsupplies from the VBUSxand VCCxsupplies respectively.
- Galvanic isolation.
