Circuit Provides Reverse-Battery Protection | Analog Devices

You can avoid damage by inserting a single diode or by using a diode-bridge configuration, but those fixes waste power and reduce the supply voltage by adding one or two diode drops between the battery and the supply rail. An alternative solution not only protects against battery-reversal damage but also automatically corrects the reversal (see

6 FAQs about [Battery reversible DC power supply function]

What happens if a capacitor reverses a power supply?

In this situation, the system capacitor’s voltage reverses the power supply, which can result in system power failure and trigger an interrupt function. During the superimposed AC input voltage test, current backflow occurs since the P-channel MOSFET is completely open.

What is the simplest protection against reverse battery protection?

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.
