Detailed Pin Configuration

ADM809LAKS-REEL has three pins:

1. VCC: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground or negative supply voltage.
3. RESET: This pin provides the reset signal output.

Functional Features

• Voltage Monitoring: ADM809LAKS-REEL continuously monitors the supply voltage and asserts the reset signal when it falls below the programmed threshold voltage.
• Adjustable Threshold Voltage: The reset threshold voltage can be adjusted to suit specific system requirements.
• Open-Drain Output: The reset signal is provided through an open-drain output, allowing easy interfacing with other devices.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Precision voltage monitoring ensures reliable operation.
• Adjustable reset threshold voltage provides flexibility.
• Small package size saves board space.

Disadvantages

• Lack of built-in hysteresis may lead to potential noise-related issues.
• Limited number of available reset threshold voltage options.

Working Principles

ADM809LAKS-REEL operates by comparing the supply voltage with the programmed threshold voltage. When the supply voltage drops below the threshold, the reset signal is asserted. The open-drain output allows the reset signal to be connected to other devices or microcontrollers.
