Description

The QT160-AS is designed as a charge-transfer ("QT") Qtouch IC which is a self-contained digital controller capable of detecting near-proximity or touch from up to 6 electrodes. The QT160-AS allows electrodes to project 6 independent sense fields through any dielectric like glass, plastic, stone, ceramic, and wood. They can also make metal-bearing objects responsive to proximity or touch by turning them into intrinsic sensors. These capabilities coupled with continuous self-calibration can lead to entirely new product concepts, adding high value to product designs.

QT160-AS has thirteen features. (1)6 completely independent touch circuits. (2)Individual logic outputs per channel (active high). (3)Projects prox fields through any dielectric. (4)Only one external capacitor required per channel. (5)Sensitivity easily adjusted on a per-channel basis. (6)100% autocal for life - no adjustments required. (7)3-5.5V, 5mA single supply operation. (8)Toggle mode for on/off control (strap option). (9)10s, 60s, infinite auto-recal timeout (strap options). (10)AKS adjacent key suppression. (11)Less expensive per key than many mechanical switches. (12)Eval board with backlighting-p/n E160. (13)Pb-free package available. Those are all the main features.

Some absolute maximum ratings of QT160-AS have been concluded into several points as follow. (1)Its storage temperature range would be from -55°C to 125°C. (2)Its Vdd would be from -0.5V to +7.0V. (3)Its max continuous pin current any control or drive pin would be +/-20mA. (4)its short circuit duration to ground any pin would be infinite. (5)Its short circuit duration to Vdd any pin would be infinite. (6)Its voltage forced onto any pin would be from -0.6V to Vdd+0.6V. The QT160-AS should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of QT160-AS are concluded as follow. (1)Its supply currnt would be typ 2.5mA and max 8mA. (2)Its supply turn-on slope would be min 100V/ns. (3)Its low input logic level would be max 0.7V. (4)Its high input logic level would be min 2V. (5)Its low output voltage would be max 0.6V. (6)Its high output voltage would be min Vdd-0.7V. And so on. If you have any question or suggestion or want to know more information of QT160-AS please contact us for details. Thank you!
