Description
B1
ID
Input,
Analog
N/A
For device applications the ID pin is connected to
VDD33
. For Host applications ID is grounded. For
OTG applications the ID pin is connected to the USB
connector.
C2
VBUS
I/O,
Analog
N/A
This pin is used for the VBUS comparator inputs and
for VBUS pulsing during session request protocol. An
external resistor, RVBUS, is required between this pin
and the USB connector.
C1
VBAT
Power
N/A
Regulator input. The regulator supply can be from
5.5V to 3.0V.
D2
VDD33
Power
N/A
3.3V Regulator Output. A 1.0uF (<1 ohm ESR) bypass
capacitor to ground is required for regulator stability.
The bypass capacitor should be placed as close as
possible to the USB333x.
