Product Introduction
The TTP229 TonTouch™ IC is a touch chip designed based on the capacitive sensing principle. This TTP229 IC integrates a voltage regulator circuit for powering the touch sensor, and its stable touch performance can be applied in various applications. The human-machine touch panel can be connected through non-conductive insulating materials, with the main application being to replace mechanical switches or buttons. This chip can independently support 8 touch keys or 16 touch keys.
TTP229 Feature
1. Operating voltage:
2.4V~5.5V (Built-in voltage regulator circuit enabled)
2.0V~5.5V(Built-in voltage regulator circuit disabled)
2. The function of enabling/disabling the built-in voltage regulator circuit can be selected externally.
3. Stand-by current
At 3V, and sleep mode slow sampling rate 8Hz：
=> Typical 2.5 uA for 16 input keys
=> Typical 2.0 uA for 8 input keys
4. Provides to set 8 keys or 16 keys by option
5. Provides to set 8 separate outputs only for 8 direct input keys mode
6. It has two serial output modes, both can use for 8 and 16 keys mode
It includes 2-wire serial mode and I2C communication mode, which are selected by the option.
7. 8 direct output ports support selection of different output types (CMOS/OD/OC with active high/low)
8. 2-wire serial mode allows selection of active high or active low via option
9. Offer multi-key or single-key feature by option
10. Provides two kinds of sampling rate that slow sampling rate 8Hz and fast sampling rate 64Hz at sleep mode
11. Have the maximum key-on time about 80sec by pin option
12. Sensitivity can adjust by the capacitance(1~50pF) outside
13. After power-on have about 0.5 sec stable-time
During the time do not touch the key pad, and all functions are disabled.
14. Auto calibration
The re-calibration period is about 4.0sec, when all keys are not activated for fixed time.
