Digital Input Sensing

Digital input/ Dry Contact input Sensing Circuit



When NC (normally closed) is detected at the input, the microcontroller will receive a Low (0V) signal and a high (5V) signal will be received for NO (normally open).

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...
