微功率、超灵敏霍尔效应开关

A3211 和 A3212 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。这些器件尤其适用于电池供电、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。2.5 至 3.5 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 15 µW 以下（2.75 V 电源电压时） 。\r\n\r\n与其他霍尔效应开关不同的是，只要北极或南极磁场强度足够大，就能打开 A3212 中的输出，没有磁场的时候，输出就会停止。A3211 提供反向输出。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开关，具有更高的可靠性并便于制造，从而降低对信号条件的要求。\r\n\r\n • 符合 AEC-Q100 标准 \r\n• 微功率操作\r\n• 使用南极或北极操作\r\n• 在 2.5 至 3.5 V 电池电压工作\r\n• 稳定斩波\r\n• 超卓的温度稳定性\r\n• 极低的开关点漂移\r\n• 对物理应力不敏感\r\n• 固态可靠性\r\n• 小尺寸\r\n• 不受磁极影响，可轻松制造;
