Disadvantages

• Fixed threshold voltage may not suit all applications
• Limited temperature range may restrict usage in extreme environments

Working Principles

The MAX6316LUK46CY-T operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or an out-of-range condition. The manual reset input allows the user to manually trigger a reset signal. The low quiescent current ensures minimal power consumption during operation.
