There are several applications at home or industry for long delay timers (ON or OFF delay). Time delays on the order of seconds can be generated using 555 timer circuits, provided the timing capacitor ...
Protect your home appliances from voltage spikes with this simple time delay circuit. Whenever power to the appliances is switched on or resumes after mains failure, the oscillator starts oscillating ...
Most watchdog-timer ICs produce a single limited-duration output pulse when the watchdog timeout expires. Some applications, however, require the output to latch. This simple circuit provides a ...
