电压检测 -> 带延时
The XZ1909 Series is a series of high-precision voltage detectors with a built-in delay time generator of fixed time. developed using CMOS process. The detection voltage is fixed internally, with an accuracy of ±2.0 %. Internal oscillator and counter timer can delay the release signal without external parts, delay times 200 mS Two output forms, Nch pen-drain and CMOS output are available.
