【通信应用笔记】使用意法半导体的电压检测器 AN2504 Application note Using STMicroelectronics Voltage Detectors 1 Introduction Voltage detectors are designed to monitor the system supply voltage and assert the output signal, OUT, every time it goes below a defined voltage threshold. The major advantages of these circuits are low current consumption and a precise temperature-compensated voltage reference, VREF (see Figure 1). STMicroelectronics voltage detectors are also laser programmed to the desired voltage threshold over the range of 1.6V to 6.0V in 100mV steps and ……
