Altium Develop gives you the collaborative platform to design smarter circuits with real-time team feedback — from schematic capture to manufacturing: altium.com/develop?utm_source=youtube&utm_medium=video&utm_campaign=schematic-capture&utm_content=reverse-polarity-protection-p-channel-mosfet-vs-fuse-explained
When it comes to reverse polarity protection, MOSFETs and diodes are the go-to solutions — but there's a passive alternative worth knowing: the PTC resettable fuse. Unlike active components, a PTC fuse requires no additional circuitry and will automatically open at high current to protect your circuit. Best of all, once current returns to a safe level, it resets on its own — no manual intervention required.
