Touch Key

BS801B/02B/04B/06B/08B具有1到8個(gè)觸摸按鍵，可用來檢測外部觸摸按鍵上人手的觸摸動(dòng)作。該系列的芯片具有較高的集成度，使用較少的外部元件便可實(shí)現(xiàn)觸摸按鍵的應(yīng)用。\n\n BS804B 和BS808B 還提供了一個(gè)單線串行接口，可方便與外部MCU之間的通訊，實(shí)現(xiàn)對芯片設(shè)置以及觸摸引腳按鍵檢測的目的。\n\n 芯片內(nèi)部集成電路具有高電源電壓抑制比，可減少按鍵檢測錯(cuò)誤的發(fā)生，這一特性保證在不利環(huán)境條件的應(yīng)用中芯片仍具有很高的可靠性。此系列的觸摸芯片具有自動(dòng)校準(zhǔn)功能，低待機(jī)電流，喚醒模式可選等特性，為各種觸摸按鍵的應(yīng)用提供了一種簡單而又有效的實(shí)現(xiàn)方法。\n\n ? 工作電壓: 2.2V~5.5V\n? 自動(dòng)校準(zhǔn)功能\n? 高電源電壓抑制比\n?
