HT8233F
產品簡述

The HT8233F is a touch pad detector IC which offers 1 touch key. The device built-in regulator for touch sensor. Stable sensing method can cover diversity conditions. The touching detection IC is designed for replacing traditional direct button key with diverse pad size.  


• Operating voltage 2.4V ~ 5.5V

• Built-in regulator for touch sensor

• Built-in low voltage reset (LVR) function

• Operating current, @VDD=3V no load 

  At low power mode typical 1.5uA, maximum 5uA

• The response time max about 220mS at low power mode @VDD=3V

• Sensitivity can adjust by the capacitance(1~50pF)outside

• Stable touching detection of human body for replacing traditional direct switch key

• Provides Low Power mode

• Provides direct output or toggle output selection by pin option (TOG pin)

• Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin)

• Have the maximum on time 16 sec

• After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled
