1. VCC: Supply voltage input
2. GND: Ground reference
3. RESET: Active-low reset output

Functional Features

The LM810M3-4.00/NOPB is designed to monitor the supply voltage of an electronic system. It provides a reset signal when the voltage drops below a specified threshold, ensuring proper operation of the system. The active-low RESET output remains low until the supply voltage rises above the threshold and the reset timeout period elapses.

Advantages and Disadvantages

Advantages

• Wide voltage range allows compatibility with various systems
• Low quiescent current minimizes power consumption
• Small package size enables space-saving designs
• RoHS compliant, ensuring environmental friendliness

Disadvantages

• Fixed threshold voltage may not be suitable for all applications
• Limited reset timeout period may not accommodate longer system startup times

Working Principles

The LM810M3-4.00/NOPB utilizes a precision voltage reference and comparator to monitor the supply voltage. When the voltage drops below the threshold, the comparator triggers the active-low RESET output, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Application Field Plans

The LM810M3-4.00/NOPB finds application in various electronic systems where voltage monitoring is critical. Some potential fields of application include:

1. Battery-powered devices: Ensures proper shutdown or warning when battery voltage is low.
2. Microcontroller systems: Provides a reliable reset signal during power-up and voltage fluctuations.
3. Industrial control systems: Monitors power supply integrity to prevent malfunctions or data corruption.
4. Automotive electronics: Protects sensitive components from voltage dips or spikes.

Alternative Models

For those seeking alternative options, several similar products are available in the market. Some notable alternatives to the LM810M3-4.00/NOPB include:

1. MAX809: Offers adjustable threshold voltage and longer reset timeout period.
2. TL7705: Provides additional features like watchdog timer and manual reset input.
3. ADM708: Features a wider operating temperature range and higher accuracy.

These alternative models offer flexibility and additional functionalities based on specific application requirements.

In conclusion, the LM810M3-4.00/NOPB is a voltage supervisor IC that ensures stable operation of electronic systems by monitoring the supply voltage. Its wide voltage range, low power consumption, and compact package make it suitable for various applications. However, its fixed threshold voltage and limited reset timeout period should be considered when selecting the appropriate voltage supervisor for a specific system.
