MOSFET-based load switches, whether as an integrated circuit (IC) or built with discrete components, continue to be popular choices for many engineers. They are favored in power-switching applications ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

How to replace MOSFETs with load switches, and the impact of on-resistance. Swapping out diodes with ideal diodes, and the use of ideal-diode controllers. Why replacing fuses and resettable fuses with ...

Find a downloadable version of this story in pdf format at the end of the story. TYPICAL HIGH-SIDE, n-channel, hot-swap “soft-switch” systems use a charge pump to drive the gate of an external MOSFET ...
