Pin Configuration

The MAX811REUS-T has the following pin configuration:

1. GND (Ground)
2. RESET (Reset Output)
3. MR (Manual Reset Input)
4. VCC (Power Supply)

Functional Features

• Monitors the power supply voltage continuously
• Generates a reset signal when the voltage falls below the specified threshold
• Provides manual reset capability through the MR pin
• Offers different reset timeout periods for flexibility in system design

Advantages and Disadvantages

Advantages: - Low-power consumption extends battery life in portable devices - Precision voltage monitoring ensures reliable system operation - Multiple reset output options cater to different system requirements - Small package size saves board space

Disadvantages: - Limited number of reset threshold options - Reset timeout periods may not be suitable for all applications

Working Principles

The MAX811REUS-T operates by comparing the power supply voltage with a preset threshold. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or unstable condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.

Application Field Plans

The MAX811REUS-T is widely used in various electronic systems that require reliable voltage monitoring and reset functionality. Some application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial control systems
4. Power management circuits
5. Communication equipment

Alternative Models

• MAX809REUR-T
