Texas Instruments TPS37xx 低功耗高精度电压检测器
德州仪器 TPS37xx 低功耗、高精度电压检测器是低功耗、小尺寸的双通道电压检测器。SENSE1 和 SENSE2 输入包含滞后特性，可抑制短小毛刺脉冲，从而确保输出操作稳定而无错误触发。这些器件具有可通过一个外部电阻分压器配置的可调感测（SENSE）输入。当 SENSE1 或 SENSE2 输入上的电压低于下降阈值时，OUT1 或 OUT2 相应降为低电平。当 SENSE1 或 SENSE2 上升到高于上升阈值时，OUT1 或 OUT2 相应变为高电平。该器件具有 2µA（典型值）的超低静态电流，这提供了一套精确且节省空间的电压检测 解决方案，适用于低功耗系统监视和 便携式应用。
These devices have adjustable SENSE inputs that can be configured by an external resistor divider. When the voltage at the SENSE1 or SENSE2 input goes below the falling threshold, OUT1 or OUT2 is driven low, respectively. When SENSE1 or SENSE2 rises above the rising threshold, OUT1 or OUT2 goes high, respectively. The devices have a very low quiescent current of 2µA (typical) and 5.5µA typical low quiescent current (TPS3710 and TPS3700).
This very low quiescent current provides a precise, space-conscious solution for voltage detection suitable for low-power system monitoring and portable applications. Additionally, the Texas Instruments TPS37xx-Q1 series are AEC-Q100 Certified for use in Automotive Applications.
