Product Summary

The QT150-AS is a 5 KEY qtouch sensor IC. The QT150-AS can also turn metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability coupled with their continuous self-calibration feature can lead to entirely new product concepts, adding high value to product designs. The applications of the QT150-AS are Instrument panels, Gaming machines, Access systems, Pointing devices, Appliance controls, Security systems, PC Peripherals, Backlighted buttons.

Parametrics

QT150-AS absolute maximum ratings: (1)Storage temp:-55℃ to +125℃; (2)VDD:-0.5 to +7.0V; (3)Max continuous pin current, any control or drive pin:±20mA; (4)Short circuit duration to ground, any pin:infinite; (5)Short circuit duration to VDD, any pin:infinite; (6)Voltage forced onto any pin:-0.6V to (Vdd + 0.6) Volts.

Features

QT150-AS features: (1)Completely independent QT touch circuits; (2)Individual logic outputs per channel (open drain); (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 to 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 (pin option); (11)Sync pin for multi-chip sync or line sync ; (12)Less expensive per key than many mechanical switches; (13)Eval board with backlighting - p/n E160.
