汽车类 600nA 超低静态电流可编程延迟监控电路

TPS3808E-Q1 系列微处理器监控电路可以监视 0.4V 至 5V 的系统电压，在 SENSE 电压降至低于预设阈值时或手动复位 ( MR) 引脚降为逻辑低电平时，发出开漏 RESET 信号。在 SENSE 电压和手动复位 ( MR) 返回至相应阈值以上之后， RESET 输出会在用户可调节延迟时间内保持低电平。\n\nTPS3808E-Q1 器件采用精密基准，可实现 0.5% 的阈值精度。通过断开 C T 引脚，可将复位延迟时间设置为 20ms；通过使用电阻将 C T 引脚连接至 V DD，可将复位延迟时间设置为 300ms，或通过将 C T 引脚连接到外部电容器，用户可在 1 • 上电复位发生器具有可调节延迟时间：1.25ms 至 10s\n• 极低静态电流：0.6µA（典型值）\n• 高阈值精度：1%（典型值）\n• 提供适用于标准电压轨的 0.9V 至 5V 固定阈值电压且可调节电压低至 0.405 V\n• 手动复位 ( MR) 输入\n• 漏极开路 复位输出\n• 温度范围：–40°C 至 125°C\n• 小型 SOT-23-6;
