Reverse-Current Circuitry Protection | Analog Devices
On the other hand, you can configure connectors for rechargeable battery packs so that momentary reverse connections are impossible unless the user modifies the connector. The greatest challenge, however, is in applications powered by one or more single-cell batteries such as AA-alkaline, NiCd, and nickel-metal-hydride types.
Protecting Vehicle Electronics from Reverse-Battery Connection
During reconnection it is possible to reverse the polarity of the battery connection, which can result in potential short-circuits and other problems with loads connected to the battery. Unfortunately, this issue isn''t entirely prevented by the mechanical design of different sized battery terminals or the use of prominent color-coding of cables, connectors and terminals.
