4 Frequently Asked Questions about "Inverter Reverse Polarity 12V Protection"

What is a reverse polarity protection circuit?

Table 5. ESTIMATED MAXIMUM TAMB Reverse polarity protection circuits are one of the core building blocks of any ECU in a vehicle. In this application note several reverse polarity protection techniques are discussed including diodes, P−Channel MOSFET and N−Channel MOFET.

Can you get reverse polarity protection with a diode?

You can, in fact, get reverse polarity protection with a diode. Yes, all you need is one diode. This really does work, but of course a more sophisticated solution could provide superior performance. The idea here is to put the diode in series with the supply line.

What happens if a reverse polarity protection circuit fails?

If the reverse polarity protection circuit does not provide a controlled return path, the current may flow through unintended structures, including MOSFET body diodes or parasitic paths inside the PCB. These currents are rarely catastrophic in a single event, but they shorten component life.

What is reverse polarity protection (RPP)?

One such standard related to reverse polarity protection (RPP) is ISO 7637−2:2011 which replicates the various voltage scenarios like in the real application and the system needs to withstand such voltages to showcase the robustness against failures.
