Functional Features

• Monitors the power supply voltage and asserts a reset signal when the voltage drops below the threshold.
• Provides a manual reset input for immediate system reset.
• Adjustable reset timeout period allows customization based on system requirements.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring helps prevent system malfunction due to low supply voltage. - Manual reset input allows for immediate system recovery. - Small package size enables space-saving integration into compact electronic devices.

Disadvantages: - Limited threshold voltage options may not cater to all voltage monitoring requirements. - External capacitor required for adjusting the reset timeout period, adding complexity to the design.

Working Principles

The MAX6313UK49D4-T continuously monitors the power supply voltage using an internal voltage reference. When the voltage drops below the threshold voltage, the reset output is asserted, indicating a power failure or unstable voltage condition. The manual reset input can be used to force an immediate system reset, regardless of the monitored voltage level. The reset timeout period can be adjusted by connecting an external capacitor to the RST pin, allowing customization based on specific system requirements.
