Pin Configuration

The MAX811LEUS-T has the following pin configuration:

| Pin Name | Description | |----------|-------------| | GND | Ground | | MR | Manual Reset Input | | RESET | Reset Output | | VCC | Supply Voltage |

Functional Features

  1. Voltage Monitoring: The MAX811LEUS-T continuously monitors the supply voltage and compares it to the preset threshold.
  2. Manual Reset: It provides a manual reset input that allows the user to manually reset the system.
  3. Reset Output: When the supply voltage drops below the threshold, the MAX811LEUS-T asserts the reset output, signaling the system to reset.
  4. Reset Timeout: The reset output remains asserted for a fixed timeout period after the supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages

  • Low-power consumption
  • Precision voltage monitoring
  • Manual reset capability
  • Small package size (SOT-143)
  • Wide operating temperature range

Disadvantages

  • Limited reset threshold options
  • Single-channel voltage monitoring

Working Principles

The MAX811LEUS-T operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the voltage drops below the preset threshold, the reset output is asserted, indicating a power failure or low voltage condition. The reset output remains active for a fixed timeout period after the voltage rises above the threshold to ensure stable operation.

Application Field Plans

The MAX811LEUS-T is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some potential application fields include:

  1. Embedded Systems: Used in microcontroller-based systems to ensure proper operation during power fluctuations.
  2. Industrial Automation: Provides voltage monitoring and reset capabilities in industrial control systems.
  3. Consumer Electronics: Used in devices such as smart home appliances, IoT devices, and wearable gadgets to ensure reliable operation.

Alternative Models
