Touch sensitivity adjustable by external capacitor (1~50pF)

● Stable touch effect replaces traditional mechanical switch

● Provide low power consumption mode

● Provide direct output mode and latch mode function selection (TOGpin).

● Qpin is CMOS output pin, which can be selected by external jumper to be active high or active low (AHLB pin)

● Maximum 16 seconds timing output

● 0.5 seconds after power-on for chip stability time, during this period of time do not approach the touch detection point, and during this period of time all the chip

Function disabled.

● Automatic calibration function. If there is no inductive touch within 8 seconds after power-on, the chip refreshes the reference value every 1 second. If there is touch induction within 8 seconds after power-on, or no inductive touch after 8 seconds of power-on, the reference value refreshes every 4 seconds.
