The OUT1 and OUT2 are an open drain structure. For this reason the connection of pull-up resistor R510 and R520 are required between OUT1, OUT2 and VDD. The reset value of OUT1 and OUT2 is high, and the value is low during a touch is detected on CS1 or CS2. Over few k? resistors are recommended as R510 and R520.

6、 Recommended Circuit (Example)

Two channel touch key board can be designed by using only one TS02N. The TS02N is embedded intelligent internal power reset circuit that makes possible to save circuit cost because of reducing external components for reset. The sensitivity calibration operation can help to prevent abnormal detection caused by external noise, temperature variation, and supply voltage drop.
