1.Touch key detection IC, providing a touch key. Touch detection IC is designed to replace traditional keys with variable key size and design. Low power consumption and wide operating voltage DC and AC touch key features.

2.Operating voltage 2.0V ~ 5.5V.

3.After power needs settling time of about 0.5sec, and this time period do not touch on the keys, In this case all functions are disabled.

4.Always self-calibration.

5.When the key is not touched, re-calibration cycle is about 4.0se.

6.PCB size:15.5*23.5mm.
