微功率、超灵敏霍尔效应开关

A3213 和 A3214 集成电路是带有锁存数字输出的超灵敏、不受磁极约束的霍尔效应开关。它们尤其适用于电池供电型、手持型设备的操作，例如移动和无绳电话、传呼机以及掌上型电脑。2.4 至 5.5 V工作电压范围和独特的时钟方法，能将平均操作功率要求降低到 825 µW（对于 A3213）和 14 µW（对于 A3214）以下（在 2.75 V时）！A3213 和 A3214 除工作循环和平均工作电流以外，其他特征均相同。\r\n\r\n与其他霍尔效应开关不同的是，只要北极或南极的磁场强度足够大，就能打开输出；没有磁场的时候，输出就会停止。不受磁极影响和最低的功率要求，允许这些器件轻松取换簧片 • 符合 AEC-Q100 标准 \r\n• 使用南极或北极操作\r\n• 稳定斩波\r\n• 极低的开关点漂移\r\n• 高度静电放电保护\r\n• 小尺寸\r\n• 不受磁极影响，可轻松制造;
