Detailed Pin Configuration

The MAX810REXR+T has three pins:

1. GND: Ground connection.
2. RESET: Active-low reset output.
3. VCC: Power supply input.

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage drops below the specified threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Low quiescent current consumption, suitable for battery-powered applications.
• Precision monitoring with tight voltage thresholds.

Advantages

• Small package size allows for space-saving designs.
• Wide supply voltage range enables compatibility with various systems.
• Multiple reset threshold options provide flexibility in different applications.
• Low power consumption extends battery life.
• Reliable reset output ensures proper system initialization.

Disadvantages

• Limited reset timeout period may not be suitable for all applications requiring longer delays.
• Single-channel design may not be suitable for systems requiring multiple voltage monitoring points.

Working Principles

The MAX810REXR+T operates by comparing the power supply voltage with a fixed threshold. When the voltage falls below the threshold, the reset output is activated, indicating a power failure or an unstable voltage condition. The reset signal remains active until the voltage rises above the threshold and stabilizes.

Detailed Application Field Plans

The MAX810REXR+T is widely used in various applications, including:

1. Microcontroller Systems: Ensures proper initialization and reliable operation of microcontrollers.
2. Embedded Systems: Provides voltage monitoring for critical components in embedded systems.
3. Industrial Control Systems: Monitors power supply integrity in industrial control applications.
4. Automotive Electronics: Ensures stable voltage levels for automotive electronic systems.
5. Battery-Powered Devices: Extends battery life by monitoring voltage levels and initiating appropriate actions.
