What is the difference between Brown-out detect and Black-out detect?

Brown-out detection and black-out detection are both related to power supply issues, but they differ in how they occur and how systems respond to them.

• Brown-out detection refers to a temporary drop in voltage that falls below the minimum required for reliable operation but does not completely cut off power. Many microcontrollers and electronic devices have brown-out reset (BOR) circuits that detect these voltage dips and trigger a reset to prevent erratic behavior.
• Black-out detection, on the other hand, refers to a complete loss of power—essentially a total shutdown. Unlike brown-outs, black-outs require a full restart once power is restored, and systems often rely on backup power sources like batteries or uninterruptible power supplies (UPS) to mitigate their effects.

Think of a brown-out like a dimming light bulb—it still has power but isn’t functioning properly. A black-out is when the light goes out completely
