2. GND: Ground reference pin.
3. RESET: Output pin for reset signal.

Functional Features

• Voltage Monitoring: The LM810M3X-2.93 continuously monitors the input voltage and compares it to the preset threshold voltage.
• Reset Signal Generation: When the input voltage falls below the threshold, the LM810M3X-2.93 generates a reset signal to initiate a system reset.
• Adjustable Timeout Period: The reset signal remains active for a user-adjustable period after the voltage rises above the threshold, allowing sufficient time for the system to stabilize.

Advantages and Disadvantages

Advantages

• High accuracy in voltage monitoring.
• Low power consumption, making it suitable for battery-powered devices.
• Wide operating voltage range enables compatibility with various systems.
• Small package size allows for space-saving designs.

Disadvantages

• Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.
• Limited timeout period adjustment range.

Working Principles

The LM810M3X-2.93 operates by comparing the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is activated. The reset signal remains active for a user-defined period after the voltage rises above the threshold, ensuring proper system initialization.
