Working Principles

The MAX6314US28D2-T operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a power failure or an out-of-range condition. The reset signal remains active until the supply voltage rises above the threshold and a timeout period elapses.

Detailed Application Field Plans

The MAX6314US28D2-T finds applications in various fields, including:

  1. Battery-powered devices: Ensures proper shutdown or system reset when battery voltage drops below a safe level.
  2. Industrial control systems: Monitors power supply integrity to prevent data corruption or equipment damage during voltage fluctuations.
  3. Automotive electronics: Provides reliable reset signals for microcontrollers and other critical components during automotive power supply variations.
  4. Home automation: Enables safe operation and protection of smart home devices during power supply anomalies.
