VKD104N
4 KEY TOUCH PAD DETECTOR IC
The
VKD10
4N
VinTouch
TM
IC is capacitive sensing design specifically for touch pad
controls. The device built in regulator for touch sensor. Stable sensing method can cover diversity
conditions. Human interfaces control panel links through non-conductive dielectric material. The
main application is focused at replacing of the mechanical switch or button. The ASSP can
independently handle the 4 touch pads with 4 direct output pins.
GENERAL DESCRIPTION
FEATURES
?
?
?
Operating voltage 2.4V~5.5V
Built-in regulator
Operating current, @VDD=3V no load
At low power mode typical 2.5uA, At fast mode typical 9uA
@VDD=3V operating voltage :
The response time about 60mS at fast mode,160mS at low power mode
Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad
Provides Fast mode and Low Power mode selection by pad option(LPMB pin)
Provides direct mode or toggle mode、CMOS output or open drain output、
active high or active low by pad option(TOG/AHLB/OD pin).
Have the maximum on time 16sec/infinite by pad option(MOT0 pin)
After power-on have about 0.5sec stable-time, during the time do not touch the key pad,
and the function is disabled
Auto calibration for life, and the re-calibration period is about 4.0sec, when key has not be
touched.
