Load switches, Part 2: IC implementations and benefits
Part 1 of this FAQ looked at the need for the load-switch function for a circuit’s DC rails, the basic implementation using a MOSEFT and driver, and the limitations of this approach. Part 2 looks at what are referred to as load switches, which in this context means ICs designed to implement the load-switch function, […]
Load switches, Part 1: Basic role and principle
Load switches are used to enable/disable power to selected ICs or circuit subsections. Although they don’t get much attention, they are useful for both saving power as well as management of multiple power rails. This FAQ will discuss their function, basic design, advanced IC implementations, and additional benefits of IC load switches. Q: What is […]
