2. MR: Manual reset input pin
3. RESET: Active-low reset output
4. VCC: Positive power supply input
5. TH: Threshold voltage selection pin

Functional Features

• Voltage Monitoring: The MAX6313UK25D4-T continuously monitors the power supply voltage and asserts the reset output when the voltage drops below the threshold level.
• Manual Reset Input: The manual reset input pin allows the user to manually assert the reset output, regardless of the monitored voltage level.
• Adjustable Reset Timeout: The reset timeout period can be adjusted using an external capacitor connected to the TH pin, allowing customization based on specific system requirements.
• Low Power Consumption: With a quiescent current of only 1µA, the MAX6313UK25D4-T minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring - Manual reset capability - Adjustable reset timeout period - Low power consumption

Disadvantages: - Limited threshold voltage options (only 2.5V available)

Working Principles

The MAX6313UK25D4-T operates by comparing the supply voltage with the threshold voltage set by the TH pin. When the supply voltage drops below the threshold, the reset output is asserted. The manual reset input allows the user to manually assert the reset output, overriding the voltage monitoring function. The reset timeout period can be adjusted using an external capacitor connected to the TH pin, providing flexibility in defining the duration for which the reset output remains asserted after the voltage returns to normal.

Detailed Application Field Plans

The MAX6313UK25D4-T finds applications in various fields, including:

1. Embedded Systems: It ensures proper system initialization by monitoring the power supply voltage and initiating a reset if necessary.
2. Battery-Powered Devices: It helps prevent damage to sensitive components by asserting a reset when the battery voltage drops below a safe level.
3. Industrial Control Systems: It provides reliable voltage monitoring and reset functionality in industrial automation and control systems.
4. Consumer Electronics: It enhances the overall reliability of consumer electronic devices by ensuring stable power supply operation.
