Figure 13. Recommended Schematic for VESA 2.0 Specification
NOTE CONCERNING THE POWER SUPPLY
VOLTAGE IN THE VESA 2.0 SPECIFICATION
According to the VESA 2.0 specification, the
ST24xy21 can be supplied by either the MONITOR
or by the HOST (using +5V on the VGA cable pin
9) power supply. The easyest way to implement this
is to use 2 diodes as described in the following
schematic. The ST24xy21 supply voltage will be
decreased by 0.6V, which is the diode forward
voltage drop, and will be below 4.5V. Nevertheless,
the ST24xy21 remains operational and no input will
be damaged if the applied voltage on any input
complies with the Absolute Maximum Ratings val-
ues.
Under this condition, the threshold voltage of the
Schmitt-Trigger (pin 7) will be decreased (as in
Table 6).
Refer to the AN627 Application Note for more de-
tailed information regarding the use and the protec-
tion of the ST24xy21 in a Monitor application.
