电压监督,推拉,有效低电平

Favorite

概览

CAT809 是一款 µP 监督电路,监控数字系统中的电源。CAT809 可在基于工业温度范围运行的应用中直接替代 MAX809。此器件会产生重置信号,当电源电压降至阈值阈值以下且电源升至该水平 140 ms 之后发出该信号。安森美半导体使用的底层浮动门极技术 AE²™ 可用于提供任何定制重置阈值。提供七个行业标准阈值以支持 +5.0 V、+3.3 V、+3.0 V 和 +2.5 V 系统。CAT809 具有推拉重置输出(有效低电平),CAT810 则具有推来重置输出(有效高电平)。电源上的快速瞬变将被忽略,在低至 1.0 V 的 Vcc 水平下都可保证输出状态正确。CAT809 采用 3 引脚 SOT-23 和 SC70 封装。
