低功耗14通道電容觸摸傳感器--Si14T
Si14T是一款具有自動靈敏度校準功能的14通道電容傳感器,其工作電壓范圍為1.8~5.0V。
Si14T可設置休眠模式來節省功耗。此時,功耗電流為3.5μA @3.3V。
Si14T具有兩種特殊功能:在通道1上的嵌入式電源鍵功能,可應用于移動手機;另外,芯片具有觸摸暫停檢測功能,通過SCT腳與Si512/522/523刷卡芯片配合,大大降低了誤觸發幾率,非常適合智能門鎖等應用。
I2C串行接口可以讀取觸摸感應的結果,觸摸強度可以被探測,分為低、中和高三種結果。
主要特性:
上電復位
自動校準靈敏度功能的14通道電容傳感器
可選擇的輸出模式
支持外部控制觸摸檢測暫停
8種靈敏度獨立可調
通過外部電阻可調節內部頻率
支持I2C串行接口
嵌入式高頻率噪聲消除電路
工作模式下電流70μA(@3.3V)
休眠模式下電流3.5μA(@3.3V)
應用范圍:
移動應用(手機/PDA/PMP等)
門鎖應用
薄膜開關
控制面板,鍵盤
觸摸屏幕應用
