LTC®2900 是一款用于具有多达 4 个电源电压系统的可设置电源监控器。可采用一个连接至设置引脚的外部阻性分压器来在 16 种预设或可调电压监控器组合中选择其一。预设电压门限在整个温度范围内的误差不超过 ±1.5%。
复位延迟时间可采用一个外部电容器来进行调节,并可采用手动复位输入和一个瞬时开关来发出具有设定宽度的复位脉冲。严格的电压门限精度要求和干扰免疫力确保了可靠的复位操作,且无误触发之忧。对于低至 1V 的 VCC,RST 保证能够处于正确的状态。LTC2900-1 具有一个漏极开路 RST 输出,而 LTC2900-2 具有一个推挽式 RST 输出。
43uA 的供电电流使得 LTC2900 成为对功耗敏感系统的理想选择,而且,它还可以通过配置来对 4 个以下的输入进行监控。这些器件采用 10 引脚 MSOP 封装或 10 引脚 3mm x 3mm DFN 封装。
