微功率、超靈敏霍爾效應(yīng)開(kāi)關(guān)

A3213 和 A3214 集成電路是帶有鎖存數(shù)字輸出的超靈敏、不受磁極約束的霍爾效應(yīng)開(kāi)關(guān)。它們尤其適用于電池供電型、手持型設(shè)備的操作，例如移動(dòng)和無(wú)繩電話、傳呼機(jī)以及掌上型電腦。2.4 至 5.5 V工作電壓范圍和獨(dú)特的時(shí)鐘方法，能將平均操作功率要求降低到 825 μW（對(duì)于 A3213）和 14 μW（對(duì)于 A3214）以下（在 2.75 V時(shí)）！A3213 和 A3214 除工作循環(huán)和平均工作電流以外，其他特征均相同。\r\n\r\n與其他霍爾效應(yīng)開(kāi)關(guān)不同的是，只要北極或南極的磁場(chǎng)強(qiáng)度足夠大，就能打開(kāi)輸出；沒(méi)有磁場(chǎng)的時(shí)候，輸出就會(huì)停止。不受磁極影響和最低的功率要求，允許這些器件輕松取換簧片 ? 符合 AEC-Q100 標(biāo)準(zhǔn) \r\n? 使用南極或北極操作\r\n? 穩(wěn)定斬波\r\n? 極低的開(kāi)關(guān)點(diǎn)漂移\r\n? 高度靜電放電保護(hù)\r\n? 小尺寸\r\n? 不受磁極影響，可輕松制造;
