8/26/2023 0 Comments How to add arduino to multisim![]() Ideally, short-circuit on one single output would not cause and disturbance on the other outputs, but report back to the CPU (using another input pin) it's lost, and the CPU could then alert higher-level system of the short-circuit. ![]() Pretty much like this, but with LM339 instead of transistor:īut since these four 1-2A outputs will drive four loads individually, we don't want the whole circuit to burn out in case of short-circuit. Therefore we've attached an 12V driven LM339 between the CPU pin and the P-channel FET driving the 1-2A output. Since we're using the Olimexino-STM32 Arduino clone, we've only got 3v3 on the CPU pins. I need all these four outputs to be short-circuit protected and such incidents detected by another input pin on the Arduino. We're developing an I/O shield for Arduino (sort of) and having four FET controlled output connectors with approximated 12V 1-2A load each. ![]()
