TTP222E-807SN touch button control chip 8 Key capacitive touch sensor switch IC TTP222 / TTP222E TonTouchTM 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. Characteristics: Operating Voltage 2.0V ~ 5.5V; Operating current at VDD = 3V typical value 80uA, the maximum 160uA; output refresh rate of about 55Hz 3V VDD = time; 64 steps sensitivity (SLSE0 ~ 5 pin option). Also available in 2-yl-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) mode and Serial (serial) mode, selected by pad option; direct mode up to eight inputs and eight outputs pad; serial interface mode up to eight input pad; fixed 4 and 3 * 2 * 3 matrix type provides up to 8 input pads; output pad option can be selected to be active high or active low; after a period of stabilization time on power during this period do not touch the keypad (key-pad), and the function is disabled, TTP222 stabilization time It is 3.5 to 4.0 seconds, and TTP222E 0.8 to 1.0 seconds. Always self-calibration, when all the key has not been touched, re-calibration cycle TTP222 is 3.5 to 4.0 seconds, and TTP222E 0.8 to 1.0 seconds.
