| Pin Name | Description | |----------|-------------| | RESET | Active-Low Reset Output | | GND | Ground | | VCC | Supply Voltage Input |

Functional Features

• Monitors the supply voltage and generates a reset signal when the voltage drops below the threshold.
• Provides an active-low reset output that remains low until the supply voltage rises above the threshold for a specified timeout period.
• Offers an adjustable reset timeout period to accommodate different system requirements.
• Consumes low power, making it suitable for battery-powered applications.
• Provides precision monitoring with a fixed threshold voltage option of 2.3V.

Advantages

• Reliable voltage supervision ensures proper system operation.
• Adjustable reset timeout period allows flexibility in system design.
• Low power consumption extends battery life in portable devices.
• Small package size (SOT-23) enables space-efficient PCB layout.
• Precision monitoring enhances system reliability.

Disadvantages

• Limited threshold voltage options may not suit all applications.
• Lack of built-in hysteresis may lead to potential noise-related issues.
• Not suitable for high-voltage applications due to the specified supply voltage range.

Working Principles

The ADM1817-R23ARTZ-R7 operates by continuously monitoring the supply voltage. When the voltage falls below the threshold voltage (2.3V), the reset output is activated and held low. The reset output remains low until the supply voltage rises above the threshold for a specified timeout period, after which it returns to its inactive state.
