Pin Description: 1. GND: Ground connection 2. RESET: Active-low reset output 3. MR: Manual reset input 4. VCC: Power supply input 5. TH: Threshold voltage selection input

Functional Features

• Voltage Monitoring: The MAX6310UK37D2-T continuously monitors the voltage level at the VCC pin.
• Reset Generation: When the voltage falls below the selected threshold, the IC generates an active-low reset signal on the RESET pin.
• Manual Reset: The MR pin allows for manual reset control by asserting a low-level signal.
• Adjustable Timeout Period: The reset timeout period can be adjusted using external timing components.
• Power-On Reset Delay: The IC ensures a stable reset signal during power-up by delaying the reset output until the supply voltage reaches a specified level.

Advantages and Disadvantages

Advantages: - Compact package size allows for space-efficient designs. - Wide supply voltage range enables compatibility with various systems. - Adjustable timeout period provides flexibility in system initialization. - Power-on reset delay ensures reliable operation during power-up events.

Disadvantages: - Limited threshold voltage options may not cover all voltage monitoring requirements. - Manual reset functionality may not be needed in all applications.

Working Principles

The MAX6310UK37D2-T operates by comparing the voltage at the VCC pin with the selected threshold voltage. When the voltage falls below the threshold, the internal circuitry generates an active-low reset signal. The reset signal remains asserted until the voltage rises above the threshold or a manual reset is triggered.

To ensure a stable reset signal during power-up, the IC incorporates a power-on reset delay. This delay prevents premature assertion of the reset signal until the supply voltage reaches a specified level.
