TTP229-BSF / 16 key touch button IC / SSOP28 Touch-sensitive switch TTP229 TonTouchTM IC chip is a design principle using capacitive touch sensing chip. This on-chip voltage regulator circuit for touch sensors, steady touch effect can be applied to a variety of different applications, human touch panel can be connected via a non-conductive insulating material, the main application is to replace mechanical switch or button, this chip can Independent support eight touch keys or touch keys 16 Features Operating voltage:. 2.4V ~ 5.5V (enabled chip voltage regulator circuit) 2.0V ~ 5.5V (disable the built-in voltage regulator circuit) to external choose to enable / disable the built-in Standby Current 3V regulator circuit voltage, low speed sampling rate 8Hz sleep mode: Enable internal regulator, the standby current => Typ 16-key mode 2.5uA => Typ 8 key mode disables the internal regulator 2.0uA , a standby current => Typ 16-key mode 2.5uA => 8-key mode provides typical 2.0uA Option selection 8 key or 16-key mode. offers eight independent direct output port is limited to 8 keys to directly output mode has two serial output, it can be used in 8 and 16 key models include a 2-wire serial mode and I2C communication mode, as selected by the option. 8 direct outputs can choose different output types (CMOS / OD / OC has a high / low active) of 2-wire serial mode option to select active high or active-low key provides option to select multiple or single bond effectively offers two sampling rate, sleep mode sampling rate 8Hz, fast sampling rate 64Hz Option choose a valid key has a maximum output time of approximately 80 seconds. sensitivity by an external capacitor (1 ~ 50pF) adjustment needs 0.5 seconds stabilization time after power during this period do not touch the button panel, all functions also touch Invalid Auto Calibration when all keys within a period of time has not been touched, chip system recalibration takes about 4.0 seconds Zarlink Shenzhen Micro Technology Co.
