How to achieve reverse polarity protection with ideal diodes
In battery operated devices which have removable batteries, you usually need to prevent the batteries from being connected the wrong way round to prevent damage to the electronics. If that is not possible by physical means you need to include some electronic protection. Physical protection can simply mean a polarized connector or a battery with […]
