Working Principles

The MAX6425UK42+T is designed to monitor the supply voltage of a digital system. It compares the voltage at the TH pin with an internal reference voltage. When the supply voltage drops below the threshold voltage, the RESET pin is driven low, indicating a reset condition. The reset remains active until the supply voltage rises above the threshold and a timeout period elapses.

Detailed Application Field Plans

Battery-powered devices: Provides reliable power monitoring and reset generation for portable electronics.
Microcontroller systems: Ensures proper operation by detecting and responding to voltage fluctuations.
Industrial control systems: Protects sensitive equipment from voltage drops and ensures system integrity.
