SL8022K Two-channel touch control chip
■SL8022K is a two-channel capacitive touch chip with two logic-control output.
▲Realization of logical function by a touch operation. Low operational difficulty and convenient.
▲ High applicability. Touching function is still effective with the existance of medium (such as glass, arcrylic, plastic, ceram, etc.) isolation.
▲ Wide range of applied voltage, which could be chosen optionally within 2.4V~5.5V.
◆Low cost. SL8022K could be drived by a si mple peripheral circuit, easy to machining.
▲High stability and good anti-interfere property. SL8022K has a value of EFT over ±2KV.
◆Under the interference of mobile phones which exist in a near-field and multi-angle situation,the touching sensitivity and response time of SL8022K proves to be fine.
●FEATURES
■The initial state of pin LO1 and LO2 after electrified depend on the input state of pin OSC before power on . Pin LO1 and LO2 output high level after power on If pin OSC is connected to VDD(High Level),; pin LO1 and LO2 output low level after power on. if pin OSC is connected to GND(Low Level),
■ A touch operation input through TI1 corresponds to logic ouput of LO1; a touch operation input through TI2 correspinds to logic output of LO2.
■ A press operation on TI1 or TI2 corresponds to the reversal of the logic output of LO1 or LO2; the state reverts to initial state after the release
