Pin Configuration

The MAX809TEUR+TG11 is a three-pin device with the following pin configuration:

1. GND (Ground)
2. RESET (Reset Output)
3. VCC (Supply Voltage)

Functional Features

• Monitors the supply voltage and asserts the reset output when the voltage falls below the specified threshold.
• Provides a precision voltage reference for accurate monitoring.
• Low-power consumption, suitable for battery-powered applications.
• Built-in glitch immunity ensures reliable operation in noisy environments.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Multiple reset threshold options provide flexibility for different applications. - Low-power consumption extends battery life. - Glitch immunity ensures reliable operation in noisy environments.

Disadvantages: - Limited number of reset threshold options may not meet the requirements of all applications. - The SOT-23-3 package may be challenging to solder for some users.

Working Principles

The MAX809TEUR+TG11 operates by continuously monitoring the supply voltage. When the voltage drops below the specified threshold, the device asserts the reset output, indicating a power failure or an out-of-tolerance condition. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX809TEUR+TG11 is commonly used in various applications that require reliable voltage monitoring and system reset functionality. Some of the typical application fields include:

1. Microcontrollers and Microprocessors: Ensures proper system initialization and prevents erratic behavior during power-up.
2. Embedded Systems: Provides a controlled reset to ensure stable operation after power interruptions.
3. Industrial Control Systems: Monitors power supply integrity to prevent damage to sensitive equipment.
4. Automotive Electronics: Protects critical systems from voltage fluctuations and ensures safe operation.
5. Portable Devices: Maximizes battery life by initiating a shutdown when the voltage drops below a certain level.
