High Voltage Monitoring/ Measuring using Microcontroller's ADC input


A voltage divider resistor network could be used for stepping the monitored voltage down to the range necessary for A/D conversion. A passive low-pass filter is used for noise rejection.

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...
