• Reset Timeout Period Options: 140ms, 560ms, 1120ms, 2240ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX810LEUR+T has three pins:

1. GND: Ground pin
2. RESET: Active-low push-pull output that goes low when the monitored voltage falls below the threshold
3. MR: Manual reset input used to force a reset regardless of the monitored voltage level

Functional Features

• Monitors the power supply voltage and provides a reset signal when it drops below the set threshold.
• Offers a manual reset input for immediate system reset.
• Provides a stable reset output during power-up and power-down sequences.
• Low power consumption makes it suitable for battery-powered applications.

Advantages and Disadvantages

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

Disadvantages: - Limited to voltage monitoring and reset functionality, not suitable for complex power management tasks. - SOT-23-3 package may require additional precautions during assembly and handling.

Working Principles

The MAX810LEUR+T operates by comparing the supply voltage with a preset threshold. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or an out-of-specification condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.

Detailed Application Field Plans

The MAX810LEUR+T is commonly used in various electronic systems where reliable voltage monitoring and system reset functionality are required. Some application fields include:

1. Microcontrollers and Microprocessors: Ensures proper system initialization and prevents erratic behavior during power-up.
2. Communication Systems: Provides a reset signal to restart the system in case of power fluctuations or failures.
3. Industrial Control Systems: Monitors power supply integrity to prevent damage to critical components and ensure safe operation.
4. Automotive Electronics: Protects sensitive electronic modules from voltage dips and transients, ensuring reliable operation.

Detailed and Complete Alternative Models

1. MAX809LEUR+T: Similar to MAX810LEUR+T but with different threshold voltage options.
2. MAX811LEUR+T: Voltage supervisor IC with an active-high push-pull output instead of active-low.
3. MAX813LEUR+T: Dual voltage supervisor IC with two independent reset outputs.
