Working Principles

The NE555PWRG4 operates based on the charging and discharging of an external timing capacitor through an internal voltage comparator. When triggered, the timing cycle begins, and the capacitor charges or discharges depending on the configuration. The output signal changes state when the voltage across the timing capacitor reaches the threshold or trigger level, depending on the operating mode.
