TK8021

TK8021 is a 1-key touch chip, which has the advantages of high sensitivity, strong anti-interference ability, waterproof and dustproof, high reliability, etc., and can widely replace traditional mechanical keys. It is mainly used for key detection in household appliances, consumer electronics, industrial control and other fields.

AiP5905 is a capacitive touch key circuit, which provides five touch key channels, and the sensitivity can be adjusted by external capacitors. Each touch key channel of AiP5905 corresponds to an output port, and the touch detection result is directly output in the form of high/low level.  

AiP5908 is an 8-key touch chip and can be adjusted through external capacitance and command configuration. AiP5908 has a built-in I2 C interface, which can be directly connected to the controller.  

AiP5916 is a capacitive touch key circuit that provides up to 16 touch key channels. Sensitivity can be adjusted via external capacitors and command configurations. Each key channel can be independently enabled/disabled, and disabled channels can be configured as general-purpose I/O for MCU I/O expansion. AiP5916 features a built-in I²C interface for direct controller connectivity.
