Specification:
Touch ic designed using capacitive sensing principle, its stable sensing method can be applied to various electronic products, and the panel medium can be a completely insulating material, which is specially designed to replace traditional mechanical switches or ordinary buttons. Provides 4 touch input and 4 direct output pins and 4 led indicators.
1. Working voltage: 2.0v～5.5v
2. The maximum power consumption is 11.5ua, and the low power consumption mode is only 4ua (both at 3v and no load)
3. The external configuration pins are set to various modes
4. High reliability, the chip has built-in de-jitter circuit, which can effectively prevent malfunction caused by external noise interference
5. Can be used on the surface of glass, ceramics, plastics and other media
6. With automatic calibration function, when no button is touched, the system recalibration cycle is about 4.0 sec
Button pads can be soldered with spring button touch
