Detailed Pin Configuration

The MAX809REUR+T10 is a three-pin device with the following pin configuration:

1. GND (Ground): Connected to the ground reference of the circuit.
2. RESET (Reset Output): Active-low reset output signal.
3. VCC (Supply Voltage): Connected to the positive supply voltage.

Functional Features

• Monitors the supply voltage and asserts the reset output when it falls below the specified threshold.
• Provides a precision monitoring solution for microprocessors and other digital systems.
• Low power consumption makes it suitable for battery-powered applications.
• Reset timeout period can be selected to meet specific system requirements.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures reliable operation of microprocessors. - Low power consumption extends battery life in portable devices. - Small package size allows for space-efficient designs. - Wide operating temperature range enables usage in various environments.

Disadvantages: - Limited number of reset threshold voltage and timeout period options. - Not suitable for applications requiring higher voltage monitoring.

Working Principles

The MAX809REUR+T10 operates by continuously monitoring the supply voltage. When the voltage drops below the selected threshold, the reset output is asserted low, indicating a system reset condition. The reset output remains low until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX809REUR+T10 is commonly used in various applications, including:

1. Microprocessor Systems: Provides reliable reset functionality to ensure proper startup and operation of microprocessors.
2. Embedded Systems: Monitors the power supply to prevent erratic behavior or data corruption in embedded systems.
3. Industrial Control Systems: Ensures stable operation of control systems by resetting them when the supply voltage falls below the specified threshold.
4. Consumer Electronics: Used in devices like smartphones, tablets, and gaming consoles to maintain system integrity during power fluctuations.
