A previously-published Design Idea outlined a polarity protection circuit that provides the correct connection of the battery to a load regardless of the battery’s orientation in its holder. The ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

Over the last couple of decades the use of rechargeable batteries has grown enormously, and for most common applications there are ASICs[1] which control battery management with very little additional ...

When the battery voltage falls below the lockout threshold, the circuit monitors the voltage of a Li-Ion battery and disconnects the load to prevent deep discharge. A vehicle that runs on batteries ...

Testing a Li-ion battery charger using its natural load (i.e., a battery) is time consuming because the charging process can take an hour or more. The test time varies widely, depending on whether you ...
