TTP229-CSE

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 ƒ Operating voltage：2.4V~5.5V ƒ Built-in regulator ƒ Stand-by current At 3V, and sleep mode slow sampling rate 8Hz：=> Typical 2.0uA ƒ Provides to set 8 separate outputs for 8 direct input keys ƒ Has a 2-wires serial output interface ƒ 8 separate outputs can select output driving types by option (CMOS/OD/OC with active high/low) ƒ 2-wires serial interface can select active high or low by option ƒ Offer multi-key or single-key feature by option ƒ Provides two kinds of sampling ...
