Working Principles

The MAX16058ATA28+T is designed to monitor the supply voltage of a digital system. It compares the input voltage against a user-selectable threshold level. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or low voltage condition. The reset remains active until the voltage rises above the threshold or a manual reset signal is applied.

The reset timeout period can be adjusted using an external capacitor connected to the CT pin. This feature allows designers to set the duration for which the reset output remains active after the voltage returns to normal. The manual reset input provides an immediate system reset when triggered.

Detailed Application Field Plans
