MOSFET Circuit Breaker
Cutting the power rapidly in the event of an overload implies monitoring the current through the load. This is usually done either by measuring the voltage difference across a series resistor, or by using a Hall-effect current sensor. This second solution is certainly appealing, but the cost of these sensors is still quite high, and they’re not all that easy to implement.
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.
