TTP229 16-Channel Touch Detector IC (SMD)

TTP229 16-Channel Touch Detector IC (SMD)

TTP229 16-Channel Touch Detector IC (SMD) The TTP229-BSF TonTouch TM IC is a capacitive sensing design specifically for touchpad controls. The device built-in regulator for a touch sensor. Featured by Sharvi Electronics A stable sensing method can cover diversity conditions. The human interface control panel links through the non-conductive dielectric material. The main application is focused on replacing the mechanical switch or button. The ASSP can independently handle the 8 touchpads or up to 16 touchpads.

Features/Specs:

• Operating voltage：2.4V~5.5V
• Built-in regulator
• Stand-by current
  At 3V, and sleep mode slow sampling rate 8Hz：
  => Typical 2.5uA for 16 input keys
  => Typical 2.0uA for 8 input keys
• Provides to set 8 direct keys or 16 direct keys by option
• Provides to set 8 separate outputs only for 8 direct input keys mode
• Has a 2-wires serial output interface, both can use for 8 and 16 direct input keys mode
• 8 separate outputs can select output driving types by option (CMOS/OD/OC with active high/low)
• 2-wires serial interface can select active high or low by option
• Offer multi-key or single-key feature by option
• Provides two kinds of sampling rate that slow sampling rate 8Hz and fast sampling rate 64Hz at sleep mode
• Have the maximum key-on time about 80sec by pin option
• Sensitivity can adjust by the capacitance(1~50pF) outside
• After power-on have about 0.5sec stable-time, During the time do not touch the keypad, and all functions are disabled
• Auto calibration for environment changing And the re-calibration period is about 4.0sec when all keys are not activated for a fixed time.

Application:

• Wide consumer products
• Waterproofed electric products

Package Includes:

• 1 X TTP229 16-Channel Touch Detector IC (SMD)
