6 FAQs about [Battery reverse current picture]

What happens if there is a reverse current?

However when there is a reverse current, the resistor will limit the flow back into the device to a safe level. The GND network limits the current through the ground pin of the high side switch by Equation 1

What is battery reversal protection?

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.

Can a reversed battery be installed backwards?

The effects of a reversed battery are critical. Unfortunately, it is difficult to guard against this situation. To make equipment resistant to batteries installed backward, you must design either a mechanical block to the reverse installation or an electrical safeguard that prevents ill effects when the reverse installation occurs.

Do you need reverse current protection for a battery-operated device?

In battery-operated devices that have removable batteries, you usually need to prevent the batteries being connected the wrong way to prevent damage to the electronics, accidental short-circuiting, or other inappropriate operation. If that is not possible by physical means, you need to include some electronic reverse current protection.

How can a battery prevent reversal?

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.

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.
