Pin Description: - VDD: Power supply input - GND: Ground reference

Functional Features

1. Voltage Monitoring: The LM810M3-4.63/NOPB continuously monitors the power supply voltage.
2. Reset Generation: When the voltage falls below the threshold voltage (4.63V), the IC generates a reset signal to initiate a system reset.
3. Reset Timeout: The reset signal remains active for a fixed timeout period (200ms) after the voltage rises above the threshold, ensuring a stable system startup.
4. Low Quiescent Current: The IC consumes minimal current (10µA) during normal operation, minimizing power consumption.

Advantages and Disadvantages

Advantages: - Compact package size enables space-efficient integration into various electronic systems. - Wide supply voltage range allows compatibility with different power supply configurations. - Low quiescent current minimizes power consumption, making it suitable for battery-powered applications. - Reset timeout feature ensures reliable system startup.

Disadvantages: - Fixed threshold voltage may not be adjustable to suit specific system requirements. - Lack of additional features such as adjustable reset timeout or hysteresis limits customization options.

Working Principles

The LM810M3-4.63/NOPB operates by comparing the power supply voltage against the predetermined threshold voltage. When the voltage drops below 4.63V, the IC triggers a reset signal, which can be used to restart or initialize the system. Once the voltage rises above the threshold, the reset signal remains active for the specified timeout period (200ms) to ensure a stable system startup.

Detailed Application Field Plans

The LM810M3-4.63/NOPB finds application in various electronic systems where voltage monitoring and reliable system reset functionality are crucial. Some potential application fields include:

1. Microcontrollers and Microprocessors: Ensures safe operation by preventing erratic behavior caused by voltage fluctuations.
2. Embedded Systems: Provides a reliable reset mechanism to initialize the system upon power-up or after a fault condition.
3. Industrial Control Systems: Safeguards critical equipment by monitoring power supply integrity and initiating a system reset if necessary.
4. Automotive Electronics: Protects sensitive electronic components from voltage variations, enhancing overall system reliability.

Detailed and Complete Alternative Models

1. MAX809: Voltage supervisor IC with adjustable threshold voltage and reset timeout period.
2. TL7705: Low-power voltage supervisor IC with a wide supply voltage range and adjustable reset timeout.
3. ADM6315: Microprocessor supervisory circuit with a watchdog timer and adjustable reset threshold.

These alternative models offer similar functionality to the LM810M3-4.63/NOPB but may provide additional features or customization options based on specific application requirements.
