The LM73100 is an integrated 5.5-A ideal diode that is typically used for power rail monitoring and protection applications . It operates from 2.7 V to 23 V with adjustable overvoltage and undervoltage protection. It provides ability to control inrush current and protection against input reverse polarity as well as reverse current conditions. It also has integrated analog load current monitoring and digital power good indication with adjustable threshold. It can be used in a variety of systems such as set-top boxes, smart speakers, handheld power tools/chargers, PC/notebooks and Retail ePOS (Point-of-sale) terminals.

The design procedure explained in the subsequent sections can be used to select the supporting component values based on the application requirement. Additionally, a spreadsheet design tool LM73100 Design Calculator is available in the web product folder.
