QT310

The QT310 charge-transfer ("QT") touch sensor ICs is a self-contained digital IC capable of detecting proximity,touch,or fluid level when connected to a corresponding type of electrode.It project sense fields through almost any dielectric like glass,plastic,stone,ceramic,and wood.It can also turn small metal-bearing objects intrinsic sensors,making QT310 respond to proximity or touch.This capability coupled with its ability to self calibrate continuously can lead to entirely new product concepts.

Applications of the QT310 are:(1)fluid level sensors;(2)moisture detection;(3)appliance controls;(4)access controls;(5)industrial panels;(6)secunity systems;(7)micro-switch replacement;(8)toys & games.

The absolute maximum ratings of the QT310 can be summarized as:(1):the parameter is operating temperature,the rating is as designated by suffix;(2):the parameter is storage temperature,the rating is -65 to +150,the unit is ;(3):the parameter is VDD,the rating is -0.5 to +6,the unit is V;(4):the parameter is max continuous pin current, any control or drive pin,the rating is ±40,the unit is mA;(5):the parameter is short circuit duration to ground,any pin,the rating is infinite;(6):the parameter is short circuit duration to VDD,any pin,the rating is infinite;(7):the parameter is Eeprom setups max write cycles,the rating is 1000000;(8):the parameter is voltage forced onto any pin,the rating is -1 to Vdd+0.5,the unit is Volts.
