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 16 touch pads with 16 direct output pins.

Main Features:
● Operating voltage: 2.4V - 5.5V
● Built-in regulator with external enable / disable option
● At low power mode typical 2.5uA
● At fast mode typical 9.0uA
● The response time about 100mS at fast mode, 200mS at low power mode for TTP224 The response time about 60mS at fast mode, 160mS at low power mode for TTP224N 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 / OD / AHLB pin)
● Provides 2 output pins TPQ0D, TPQ2D that have no diode protection, active low
● Have the maximum on time 120sec / 64sec / 16sec / infinite by pad option (MOT1, 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
