Detailed Pin Configuration

The MAX810LEUR-T has a simple pin configuration with three pins:

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

Functional Features

• Monitors the power supply voltage and asserts the reset signal when the voltage drops below the specified threshold.
• Provides a debounced active-low reset output to ensure proper system initialization.
• Offers a fixed reset timeout period to prevent false resets during power-up or voltage transients.

Advantages and Disadvantages

Advantages

• Low-power consumption, suitable for battery-powered applications.
• Small package size allows for space-efficient designs.
• Wide supply voltage range enables compatibility with various systems.
• Fixed reset timeout period ensures reliable system reset.

Disadvantages

• Limited reset threshold options may not meet the requirements of all applications.
• Lack of adjustable reset timeout period may be a limitation in certain scenarios.

Working Principles

The MAX810LEUR-T operates by continuously monitoring the power supply voltage. When the voltage drops below the specified threshold, the reset output is asserted low, indicating a system reset. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX810LEUR-T is commonly used in various applications where reliable microprocessor operation is critical. Some of the typical application fields include:

1. Embedded Systems: Provides a robust reset mechanism for microcontrollers and microprocessors in embedded systems.
2. Industrial Control Systems: Ensures proper initialization and reliable operation of control systems in industrial environments.
3. Automotive Electronics: Facilitates safe and reliable operation of automotive electronic control units (ECUs).
4. Consumer Electronics: Enhances the stability and reliability of consumer electronic devices such as smart home appliances and IoT devices.
