Working Principles

The MAX6423US20+T operates by continuously monitoring the supply voltage of a digital system. When the voltage falls below the specified threshold, the IC generates an active-low reset signal. This reset signal remains active until the voltage rises above the threshold or a manual reset is triggered. The reset timeout period can be adjusted or set to a fixed value, determining how long the reset signal remains active after the voltage returns to normal.

Detailed Application Field Plans

The MAX6423US20+T finds application in various fields where reliable voltage supervision and reset generation are crucial. Some potential application areas include: - Microcontroller-based systems - Microprocessor-based systems - Digital communication devices - Industrial control systems - Automotive electronics - Battery-powered devices
