• Pin 1: GND (Ground)
• Pin 2: RESET (Reset Output)
• Pin 3: VCC (Supply Voltage)

Functional Features

• Monitors the supply voltage and asserts the reset output when the voltage drops below the threshold.
• Provides an adjustable reset timeout period to accommodate different system requirements.
• Low quiescent current consumption makes it suitable for battery-powered applications.
• Offers a small package size, enabling space-constrained designs.

Advantages

• High precision in monitoring the supply voltage ensures reliable system operation.
• Low power consumption extends battery life in portable devices.
• Small package size allows for compact circuit board layouts.
• Adjustable reset timeout period provides flexibility for various system configurations.

Disadvantages

• Limited threshold voltage options may not cater to all voltage monitoring needs.
• Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.

Working Principles

The LM810M3X-4.63 is designed to monitor the supply voltage of a microprocessor or other digital systems. It compares the supply voltage with a fixed threshold voltage (in this case, 4.63V) and asserts the reset output when the supply voltage drops below the threshold. The reset output remains active until the supply voltage rises above the threshold and the adjustable reset timeout period elapses.
