Контрольные цепи MAX16053AUT+T

Схема контроля напряжения , 28В питание, выход сброса с активным высоким, с открытым стоком

The MAX16053AUT+T is a high voltage, adjustable sequencing/supervisory circuit in 6 pin SOT-23 package. This miniature device offer very wide flexibility with an adjustable voltage threshold and an external capacitor adjustable time delay. Device is ideal for use in power supply sequencing, reset sequencing and power switching applications. Multiple device can be cascaded for complex sequencing applications. A high-impedance input (IN) with a 0.5V threshold allows an external resistive-divider to set the monitored threshold. The output (OUT) asserts high when the input voltage rises above the 0.5V threshold and the enable input (EN) is asserted high. The device provide a capacitor programmable delay time from when the voltage at IN rises above 0.5V to when output is asserted. It is used in computers/servers, intelligent instruments, set-top boxes, telecom and ideal for use in power supply sequencing, reset sequencing and power switching applications.
