What is a break-before-make circuit?

There are load switch ICs incorporating two switches. After the load switch IC “breaks” one switch, the break-before-make circuit keeps two switches off until it “makes” the other switch. This prevents two voltage domains from being short-circuited during the changeover between two switches.
