Detailed Pin Configuration

The MAX810LEUR+TG002 is a three-pin device with the following pin configuration:

1. GND (Ground): Connected to the ground reference of the system.
2. RESET (Reset Output): Provides an active-low reset signal to the system when the monitored voltage falls below the threshold.
3. VCC (Supply Voltage): Connected to the positive supply voltage of the system.

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage drops below the specified threshold.
• Reset output remains low for the duration of the reset timeout period after the voltage rises above the threshold.
• Low quiescent current consumption.
• Built-in glitch immunity ensures reliable operation in noisy environments.

Advantages and Disadvantages

Advantages: - Compact SOT-23-3 package allows for space-saving integration. - Wide supply voltage range enables compatibility with various systems. - Multiple threshold voltage and reset timeout period options provide flexibility for different applications. - Low power consumption prolongs battery life in portable devices.

Disadvantages: - Limited number of threshold voltage options may not cater to all specific requirements. - Lack of adjustable reset timeout period limits customization possibilities.

Working Principles

The MAX810LEUR+TG002 operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a system reset condition. The reset output remains active for the duration of the reset timeout period after the supply voltage rises above the threshold. This ensures that the system remains in a reset state long enough for proper initialization and stable operation.

Detailed Application Field Plans

The MAX810LEUR+TG002 is widely used in various electronic systems where reliable power supply monitoring and system reset functionality are crucial. Some application fields include:

1. Microcontrollers and Microprocessors: Ensures proper initialization and prevents erratic behavior due to voltage fluctuations.
2. Embedded Systems: Provides a reliable reset mechanism for stable operation during power-up and power-down sequences.
3. Industrial Control Systems: Monitors power supply integrity to prevent damage or data corruption in critical control applications.
4. Automotive Electronics: Protects sensitive electronic components from voltage transients and ensures safe system operation.
