The reverse battery protection circuit also saves the electronics circuit by any back current from the battery. A reverse battery protection circuit can be built using a diode, MOSFET or BJT. In this tutorial, reverse battery protection circuit from each of these components will be designed and tested for power efficiency with different loads.
A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.
Reverse Current Protection is a mechanism or circuit that aims to prevent the flow of electrical current in the opposite direction of its intended operation. When the voltage at the output of a system exceeds the input voltage, reverse current flow occurs.
Reverse Current Protection using Diode is a fundamental and necessary use of a diode. It entails incorporating a diode into a circuit’s power supply in order to prevent the flow of reverse current. When a diode is connected in series with the power supply, it acts as an open circuit when the battery is connected in reverse polarity.
In general, these batteries offer no mechanical means for preventing the reversal of one or more cells. For these systems, a designer must ensure that any flow of reverse current is low enough to avoid damaging the circuit or the battery. A variety of circuits can provide this assurance.
The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. Figure 1. Diode in Series With Battery In Figure 1, the diode becomes forward biased and the load’s normal operating current flows through the diode.
