Pulse Width Stretcher using 555 Timer IC


This circuit will invert and stretch the short period active low input signal as below.


Required pulse width can be calculated by using this equation.



Hot-Swap Circuits with Inrush Current Limiter

  To provide continuous current sensing and limiting, this hot-swap circuit uses a PNP transistor and a current sense resistor of 0.333R. Wh...
