TPS3860x0 系列电源监视器 (SVS) 可以在 0.25%（典型值）的阈值精度下监控 4 个高于 0.4V 的电源轨和 1 个低于 0.4V（包括负电压）的电源轨。当 SENSEm 输入电压下降至编程阈值以下时，4 个监视电路中的每一个 (SVS-n) 都会给出 RESETn 或 RESETn 输出信号。您可以使用外部电阻器对各个 SVS-n 的阈值进行编程（其中 n = 1、2、3、4，m = 1、2、3、4L、4H）。\n\n每个 SVS-n 都具有释放 RESETn 或 RESETn 之前的可编程延迟。您可以通过 CTn 引脚连接独立设置各个 SVS 的延迟时间，允许的取值范围为 1.4ms 至 10s。只有 SVS-1 具有低电平有效手动复位 (MR) 输入；当 MR 得到的是逻辑低电平输入时，会给出 RESET1 或 RESET1。\n\nSVS-4 使用两个比较器来监控阈值窗口。您可以将额外的比较器配置为第五个 SVS，以通过电压基准输出 VREF 来监控负电压。\n\nTPS3860x0 具有 11µA（典型值）的超低静态电流，且采用了小型 4mm x 4mm VQFN-20 封装。

The TPS386000-Q1 family of voltage supervisors can monitor four power rails that are greater than 0.4 V and one power rail less than 0.4 V (including negative voltage) with a 0.25% (typical) threshold accuracy. Each of the four supervisory circuits (SVS-n) assert a RESETn or RESETn output signal when the SENSEm input voltage drops below the programmed threshold. With external resistors, the threshold of each SVS-n can be programmed (where n = 1, 2, 3, 4 and m = 1, 2, 3, 4L, 4H).\n\nEach SVS-n has a programmable delay before releasing RESETn or RESETn. The delay time can be set from 1.4 ms to 10 s through the CTn pin connection. Only SVS-1 has an active-low manual reset (MR) input; a logic-low input to MR asserts RESET1 or RESET1.\n\nSVS-4 monitors the threshold window using two comparators. The extra comparator can be configured as a fifth SVS to monitor negative voltage with voltage reference output VREF.\n\nThe TPS386000-Q1 device has a very low quiescent current of 12 µA (typical) and is available in a small, 4-mm × 4-mm, VQFN-20 package.
