Industry Expert Bill Schweber Explains…..
To minimize power consumption, a simple MOSFET is often used to gate power to unused circuits. However, a better option is to use a load switch as it has additional functions to handle the many subtleties and vagaries of power rail management.
Load switches are offered with an array of performance parameters and ratings from multiple vendors, which enables a good fit between application priorities and available parts. Schweber’s article is featured on Digi-Key’s website – http://bit.ly/2HVqSvj
