DevGuard 24
A small inline board that adds reverse-polarity, transient, and resettable overcurrent protection to 3–24 V DC projects.
Protection
Three simple layers.
Reverse polarity
A P-channel MOSFET blocks power when the source is connected backward without adding a series diode to the normal current path.
Transient clamp
A TVS diode clamps short voltage spikes before they reach the protected circuit.
Resettable fuse
A polyfuse limits sustained fault current and resets after the fault is removed and the device cools.
