R&D Kit Kit TTP223 SOT23-6 One-touch key detecting IC (Pack of 10) Automotive Electronic Hobby Kit

The TTP223 is a touch pad detector IC which offers one touch key, designed for replacing traditional direct key button switch with diverse pad size. Low power consumption and wide operating voltage are the contact key features for dc or ac application.The circuit can be interfaced to any microcontroller through the 3-pin header J1. Recommended VCC is regulated 5V, and the available output (OUT) is active-high (H) in case of a finger touch at the touch pad (TP). LED 1 (green) is the power (PWR) indicator, and LED 2 (red) is an optional output status (OUT) indicator. Just bridge the solder jumper JP1 to enable the output status indicator, if necessary.
