Consider the circuit below. You can use one diode and a voltage divider plus an opamp comparator. Forum For Electronics Designing An Rc Debounce Circuit Maya S Programming App Note Battery Charger Load Switch Approximates Ideal A proposed pin diode switch circuit is to be used to protect the sensor. Diode switch circuit . Supplemental material on pin diode physics is included in the appendices section of the handbook. The following circuit explains the diode acting as a switch. Diode switching circuits diodes can perform switching and digital logic operations. The circuit is currently connected to turn on at 5v if you want it to do the opposite turn off at 5v exchange the positions of pin 2 and 3. Ive placed a schematic on below it will show you how to connect it. At a minimum an rf switch based on pin diodes needs a dc blocking capacitor to p...
