TTP226-809SN / 8-key capacitive touch sensor switch IC TTP226TonTouchTM is a contact plate detection (touch pad detector) IC, providing 8 contacts key. Contact detection IC is designed for replacing traditional fixed-size direct button key pad. Low power consumption and wide operating voltage are the contact key features for DC or AC application. Features Operating Voltage 2.0V ~ 5.5V Operating current at VDD = 3V typical value 80uA, the maximum refresh rate 160uA output at VDD = 3V at about 55Hz 64 steps sensitivity (SLSE0 ~ 5 pin option) additionally provides two kinds of base Order (base-step) (OPST pin option) stable human contact detection, to replace the traditional switch directly bond (direct switch key) direct (direct) mode, matrix (matrix), and serial (serial) mode, the pad option direct mode up to eight inputs and eight outputs pad; serial interface mode up to eight input pad; fixed 2 * 3 * 4 and 3 matrix type provides up to eight input pads output by pad option high or active-low on power after a period of stabilization time, during which do not touch the keypad (key-pad), and the function is disabled, TTP226 0.8 to 1.0 seconds are always self-calibration, when all When the key is not to be touched, re-calibration cycle TTP226 0.8 to 1.0 seconds widely used consumer products to replace key button Zarlink Shenzhen Micro Technology Co.
