QT1101

      The QT1101 is designed as 10 Key QTouch sensor IC with typical applications of MP3 players, mobile phones, PC peripherals, television controls, pointing devices and remote controls.
      QT1101 has many features.The first one is that it would have patented charge-transfer ('QT') design.The second one is that it would have ten independent QT sensing fields (keys).The third one is that it would have 2.8V ~ 5.5V single supply operation.The fourth one is it would have 40A current typ @ 3V in 360ms LP mode.The fifth one is that it would be 100% autocal for life - no adjustments required.The sixth one is that it would have serial one or two wire interface with auto baud rate.The seventh one is that it would have fully debounced results.The eighth one is that it would have patented AKS adjacent key suppression.The ninth one is that it would have spread spectrum bursts for superior noise rejection.The tenth one is that it would have sync pin for excellent LF noise rejection.The next one is that it would have 'Fast mode' for use in slider type applications.The last one is that it would have RoHS compliant 32-QFN, 48-SSOP packages.That are all the features.
      Some absolute maximum specifications of  QT1101 have been concluded into several points as follow.The first one is about its operating temperature which would be from -40 to +85°C.The second one is about its storage temperature which would be from -50 to +125°C.The third one is about its Vdd which would be from -0.3 to +6.0V.The fourth one is about its max continuous pin current, any control or drive pin which would be ±20mA.The fifth one is about its short circuit duration to ground or Vdd, any pin which would be infinite.The sixth one is about its voltage forced onto any pin which would be from -0.3V to (Vdd + 0.3) Volts.For the recommended operating conditions The first one is about its operating temperature which would be from -40 to +85°C.The second one is about its Vdd which would be from +2.8 to +5.0V.The third one is about its short-term supply ripple+noise which would be ±5mV/s.The fourth one is about its long-term supply stability which would be ±100mV.The fifth one is about its Cs range which would be from 2.2 to 100nF.The last one is about its  Cx range which would be from 0 to 50pF.And so on.For more information please contact us.
