QT320

The QT320 charge-transfer ("QT") Q touch ICs are self-contained digital controllers capable of dete cting near-proximity or touch from up to 6 electrodes.They allow electrodes to project 6 independent sense fields through any dielectric like glass,plastic,stone,ceramic,and wood.It can also turn small metal-bearing objects intrinsic sensors,making them 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 QT320 are:(1)light switches;(2)appliance controls;(3)access systems;(4)instrument panels;(5)computer peripherals;(6)security systems;(7)pointing devices;(8)entertainment devices.

The absolute maximum ratings of the QT320 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 isvoltage forced onto any pin,the rating is -0.5 to Vdd+0.5,the unit is Volts.
