Accidentally connecting a battery reverse can be a real killer in electronic circuits. There are a number of ways to provide protection and all have the expected advantages and disadvantages. Any protection device connected in series with the battery reduces its voltage, and when the battery voltage is only in the order of 1.5 or 3V, every lost millivolt is significant. The highlight of this article is the use of a very low loss active or synchronous rectifier in low voltage applications.
