4 Key TouchPad Detector IC TTP224N-BSB SSOP-16 Package

4 Key TouchPad Detector IC TTP224N-BSB SSOP-16 Package The TTP224N-BSB TonTouch TM IC is a capacitive sensing design specifically for touchpad controls. Featured by Sharvi Electronics The device built-in regulator for a touch sensor. A stable sensing method can cover diversity conditions. The human interface control panel links through the non-conductive dielectric material. The main application is focused on replacing the mechanical switch or button. The ASSP can independently handle the 4 touchpads with 4 direct output pins.

Features/Specs:

• 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 touchpad
• 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 keypad, and the function is disabled
• Auto calibration for life and the re-calibration period is about 4.0sec when the key has not to be touched
• Package: SSOP-16 

Application:
