WebThe third image shows a simple trick for reverse polarity protection that has a minimal voltage drop across the protection device. In this case, you use an N-channel MOSFET on the return (negative) side of your project. When the DC voltage is connected properly, the MOSFET's gate is pulled high relative to its source, which turns it ON.

WebShort Circuit 3.8 Input Reverse Polarity Protection In applications such as PLC systems, the input side needs reverse polarity protection against any field supply mis-wiring. A blocking diode is the simplest means of protecting against reverse polarity connections. Since no control signal is required, circuit complexity and component count are ... WebIt is often useful to provide protection against accidental reverse polarity for your circuits. This brief review will explore three simple methods for adding this protection to your projects. For a more in-depth tutorial, see this article. Simply using a diode as shown in the first circuit is often a good approach. WebMOSFET is shown in Figure 1. The protection circuit incorporates inrush current control using P-MOSFET, a series diode to block the reverse current as well as reverse polarity, a fuse for overload or short-circuit protection, and comparator logic to disconnect the power path during undervoltage or overvoltage events. blue ridge railroad trail
