TTP224B-BSBN/TTP224B-BSB TonTouchTM IC is a touch IC designed using capacitive sensing principle. This IC has a built-in voltage regulator circuit for touch sensors, and the stable sensing effect can be applied to a wide range of electronic products. The panel media must be a completely non-sourced material, designed to replace traditional mechanical switches or normal keys. Provides 4 touch input ports and 4 direct output ports.
