The CT8233L / HX is a single-channel capacitive touch detection chip used to replace traditional mechanical switches.
Working voltage: 2.4~5.5V
Working current:
Standard sensitivity low power consumption mode: 1.5uA@3.0V No load
High sensitivity fast mode: 6.0uA@3.0V No load
Complete initialization within 0.5s after power-on is stable
Environment adaptive function, which can quickly deal with similar application scenarios such as power-on before covering media, touch power-on and so on
Reliable power-on reset (POR)
Built-in dithering circuit can effectively prevent misoperation caused by external noise interference
The maximum output time of the button is about 16s
High/low level effective output, synchronization/hold mode can be set
Standard/high sensitivity, low power consumption/fast mode can be selected
CMOS push-pull output: CT8233LF/LQ/HQ
NMOS open drain output: CT8233LK/LQK/HK
Packaging form: SOT23-6L
