Datasheet Summary
Preliminary
TTP229-CSE TonTouchTM
8 KEYS TOUCH PAD DETECTOR IC
GENERAL DESCRIPTION
The TTP229-CSE TonTouchTM IC is capacitive sensing design specifically for touch pad controls. The device built in regulator for touch sensor. Stable sensing method can cover diversity conditions. Human interfaces control panel links through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button. The ASSP can independently handle the 8 touch pads.
Features
