Description

• Operating voltage 2.0V~5.5V
• Operating current @VDD=3V, no load, SLRFTB=1
• The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V
• Sensitivity can adjust by the capacitance (0~50pF) outside
• Have two kinds of sampling length by pad option (SLRFTB pin)
• Stable touching detection of a human body for replacing traditional direct switch key
• Provides Fast mode and Low Power mode selection by pad option (LPMB pin)
• Provides direct mode?toggle mode by pad option (TOG pin)
• Open drain mode by bonding option, OPDO pin is open drain output, Q pin is CMOS output
• All output modes can be selected active high or active low by pad option (AHLB pin)
• Have the maximum on time 100sec by pad option (MOTB pin)
• Have external power-on reset pin (RST pin)
• After power-on have about 0.5sec stable-time, during the time do not touch the keypad and the function is disabled
