Detailed Pin Configuration

The MAX815TESA+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 continuously.
• Generates a reset signal when the voltage falls below the specified threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Offers adjustable reset threshold voltage and timeout period options.
• Low quiescent current consumption for power-sensitive applications.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable reset threshold and timeout options provide flexibility.
• Low-power consumption makes it suitable for battery-powered devices.
• Stable reset output ensures reliable system operation.

Disadvantages

• Limited number of reset threshold voltage and timeout period options.
• SOT-23-3 package may not be suitable for all applications.
• Not suitable for high-temperature environments above 85°C.

Working Principles

The MAX815TESA+T operates by continuously monitoring the power supply voltage connected to its VCC pin. It compares the voltage against the set threshold value and generates a reset signal when the voltage falls below this threshold. The reset signal remains active until the voltage rises above the threshold or the timeout period elapses.

Detailed Application Field Plans

The MAX815TESA+T is commonly used in various applications, including:

1. Microcontrollers: Ensures reliable system startup and operation.
2. Embedded Systems: Provides power-on reset functionality.
3. Industrial Control Systems: Monitors power supply integrity.
4. Battery-Powered Devices: Prevents erratic behavior during low battery conditions.
5. Automotive Electronics: Ensures proper functioning of critical systems.
