    I need to ship you these circuit boards for diagnosis. I have an OEM gear selector for an ICE powered car. It has 5 buttons and associated LEDs. It normally outputs a CAN or LIN bus based signal. But I just need it to output a "to ground" signal from each switch. What I would like to do is ship you the circuit boards and a spare connector with the pins. I need the LEDs associated with each of the 5 switches to illuminate when each switch is engaged, and the unit sends out a “to ground” output from each of the 5 functions, via the connector leads in the attached image. I tried to just solder on leads to the switch contacts of the larger board, but the leads and solder would not adhere. One can see in the image where the large board was burned at the ...

While IGBT's and MOSFET's are used for very similar applications it should be noted there are two main differences, the MOSFET tends to lean towards high frequency low-power switching whereas the IGBT leans towards lower frequency and harsher switching conditions, these are just the common assumptions. Due to the fairly ruggedised features of the IGBT they normally have around a 10us short-circuit capability and a higher voltage rating which makes them a lot easier to protect. The MOSFET ...

Another input from the raspberry pi called GPIO controls the gate circuit with 3.3 volts. When the GPIO signal is HIGH, it will open the gate and allow a 3.3V square signal to pass to the output (input ). When the GPIO signal is LOW, it will shut the gate circuit and output will be 0V. Circuit must be tested in LTSpice using the attached 'Input ' for the input signal, and using the attached 'GPIO PWL ' as the GPIO signal.
