Beating Discrete solutions with Integrated Load Switches - Protection

Description

July 25, 2019

Power path protection, such as short circuit protection, requires additional components to be done discretely. Also, prudent thermal design needs to ensure that the pass FET does not exceed SOA. Some load switches, such as the TPS22919, contain protection features that are difficult or impossible to implement discretely. Features such as self-protection and recovery from short circuits and thermal shutdown help protect the system.
