Vishay Semiconductors
Figure 2 shows an example of a typical application
with a separate supply voltage V
transceiver with the IRED Anode connected to the
unregulated battery V
peak load of the regulated power supply and saves
therefore costs. Alternatively all supplies can also be
tied to only one voltage source. R1 and C1 are not
used in this case and are depending on the circuit
design in most cases not necessary.
In figure 2 an option is shown to operate the
transmitter at two different power levels to switch for
long range to low power mode for e.g. saving power
for IrDA application but use the full range specification
for remote control. The additional components are
marked in the figure.
For operating at RS232 ports TOIM4232 is
recommended as ENDEC.

In the description, already different I/Os are
mentioned. Different combinations are tested and the
function verified with the special drivers available
from the I/O suppliers. In special cases refer to the
I/O manual, the Vishay application notes, or contact
