GROUND
GROUND
3V3OUT
internal 3.3v supply to the USB transceiver cell and the RSTOUT# pin. A small amount of current
(<=5mA) can be drawn from this pin to power external 3.3v logic if required.
GROUND
SWVCC
and Q1 MOSFET power switch. R5 and C3 control the power-up rate to help limit inrush current.
GROUND
VCC-IO
When interfacing with 3.3v external logic, connect VCC-IO to the 3.3v supply of the external logic;
otherwise, connect to the VCC to drive out at 5v CMOS level. This pin must be connected to VCC
from the target electronics or EXTVCC.
EXTVCC
PORTVCC if the module is to be powered by the USB port (typical configuration).
PORTVCC
USB port (typical configuration). 500mA is the maximum current available to the DLP-245SY-G
and target electronics if the USB device is configured for high power.
