GP2W0110YPS/GP2W0114YPS

Low Power Infrared Transceiver

ELECTRICAL DESIGN APPLICATION TIPS

The only external component needed for the

GP2W0110YPS/GP2W0114YPS is a capacitor for fil-

tering any power supply noise.

Application Circuit and External

Passive Components

The value of the external component CX in these

examples is a nominal 10 ÂµF/6.3 V. However, it should

be adjusted as necessary for power supply noise and

frequency.

VLEDA may be connected to VDD or driven sepa-

rately from a different voltage source that is within the

allowed range. The recommended operating voltage

range for VDD is 2.0 V to 3.6 V, and the operating range

for VLEDA is 2.0 V to 6.0 V.

An example of Split Voltage Source design is shown

in Figure 7. VDD provides power only to the receiver

electronics. This regulated source can be at a lower

potential than VLEDA (the voltage source for the LED).

The VLEDA voltage may be directly driven from the

battery as shown in Figure 7. The VDD associated with

the Receiver interface electronics may be supported by

a power regulator or other device providing an efficient

regulated lower voltage source. This voltage may be as

low as 2.0 V to 3.6 V, and the VLEDA potential may

range from 2.0 Volts to 6.0 Volts.

An alternative is to connect the VLEDA and VDD pins

together as shown in Figure 8. This arrangement

allows the GP2W0110YPS/GP2W0114YPS to be used

in existing applications where both of these voltage

sources are connected. It is footprint and interface

compatible with previous SHARP GP2W0102YP/

GP2W0104YP/GP2W0106YP products.
