Start-up delay circuit

The utility model relates to the technical field of Internet of Things communication modules, in particular to a startup delay circuit, which comprises a power supply and a delay capacitor, and is characterized in that after the delay capacitor receives a startup signal, the power supply charges the delay capacitor; the switching circuit is connected with the time delay capacitor, and the switching circuit is switched off or switched on according to the charging state of the time delay capacitor; one end of the starting-up circuit is connected with the switching circuit, the other end of the starting-up circuit is connected with the load circuit, after the time-delay capacitor completes charging and the switching circuit is closed, the starting-up circuit sends a starting-up signal to the load circuit, and the power supply supplies power to a load. Therefore, the problems of high cost and poor stability caused by the fact that startup delay is realized by adding a delay chip in related technologies are solved
