TTP224B-RO8N

TTP224B-RO8N 2 keys Touch Pad Detector IC Outline z The TTP224B-RO8N TonTouchTM 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 2 touch pads with 2 direct output pins Characteristic z Operating voltage 2.4V ~ 5.5V z Built-in regulator z Operating current, @VDD=3V no load At low power mode typical 2.5uA, At fast mode typical 13uA z @VDD=3V operating voltage : The response time about 160mS at low power mode, 60mS at fast mode z Sensitivity can adjust by the capacitance（1~50pF）outside for each touch pad z Provides direct mode or toggle mode active high or active low by pad option (TOG/AHLB pin) z After power-on have about 0.5sec stable-time, during the time do not tou...
