WAS4736
MIC/GND Cross-point Switch for CITA and
OMTP Mobile Audio Key Application
WAS4736
http://www.sh-willsemi.com
Descriptions
The WAS4736 is an audio jack detection switch for
CITA and OMTP 4-pole accessories. The pin MIC is on
audio key side, as WAS4736' O1/O2 is plugged into
audio jack of cell phone, it will detect the locations of
ground (GND) and microphone (MIC) poles on the
audio plug and automatically routes them to the
appropriate connections.
SOT-353(SC70-5)
The MIC switch' Ron is 5 Ω (typical) while the Ground
switch has a low Ron of 0.5 Ω (typical) to minimize
voltage drop across it, preventing undesired increase
in ground reference voltage.
As VCC is power-up, WAS4736 is enabled and it
consumes ultra-low quiescent current, less than 600nA
(typical). The range of signal swing in transmission can
be rail-to-rail (0~VCC), even WAS4736 can tolerate
signal swing higher than VCC but less than VCC+3V
with very little inverse leakage into VCC supply and not
any damage of the device. The speed of signal is
recommended not more than 300KHz.

Note:
1. “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating
and operation of the device at these or any other conditions beyond those indicated in the operational
sections of this specification is not implied.
2. The input and output negative voltage ratings may be exceeded if the input and output diode current
ratings are observed.
