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
