Packaging/Quantity

ADM1813-5ARTZ-RL is typically packaged in reels, with 3000 units per reel.

Specifications

• Supply Voltage Range: 1.8V to 5.5V
• Threshold Voltage Options: 2.93V, 3.08V, 4.38V, 4.63V
• Reset Timeout Period Options: 140ms, 560ms, 1120ms, 2240ms

Detailed Pin Configuration

ADM1813-5ARTZ-RL has three pins:

1. VDD: Power supply input pin (+1.8V to +5.5V)
2. GND: Ground reference pin
3. RESET: Active-low reset output pin

Functional Features

• Monitors the voltage level continuously
• Generates a reset signal when the voltage drops below the set threshold
• Reset signal remains active until the voltage rises above the threshold for the specified timeout period
• Low supply current ensures minimal power consumption

Advantages

• Wide operating voltage range allows compatibility with various systems
• Precision voltage threshold ensures accurate monitoring
• Small form factor package enables space-saving designs
• Low supply current minimizes power consumption

Disadvantages

• Limited options for threshold voltage and reset timeout period
• Lack of additional features such as hysteresis adjustment

Working Principles

ADM1813-5ARTZ-RL utilizes a voltage comparator to continuously monitor the input voltage. When the voltage falls below the set threshold, the reset output is activated. The reset signal remains active until the voltage rises above the threshold for the specified timeout period.
