Detailed Pin Configuration

ADM1813-10ARTZ-RL has three pins arranged as follows:

```

---

| | --| VDD |-- Pin 1: Power Supply Input (1.2V to 5.5V) --| RESET |-- Pin 2: Reset Output --| GND |-- Pin 3: Ground |_______| ```

Functional Features

1. Voltage Monitoring: ADM1813-10ARTZ-RL continuously monitors the supply voltage and compares it with the reset threshold voltage.
2. Reset Output: When the supply voltage falls below the reset threshold, the RESET pin goes low, indicating a reset condition.
3. Reset Timeout: The reset output remains low for a fixed timeout period (140ms typical) after the supply voltage rises above the reset threshold.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Low quiescent current minimizes power consumption.
• Small package size enables space-efficient designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Fixed reset timeout period may not be suitable for all applications.
• Limited number of pins restricts additional functionality without external circuitry.

Working Principles

ADM1813-10ARTZ-RL utilizes an internal voltage comparator to monitor the supply voltage. When the voltage drops below the reset threshold, the comparator triggers the reset output, indicating a reset condition. The reset output remains low for a fixed timeout period after the voltage rises above the reset threshold.

Detailed Application Field Plans

ADM1813-10ARTZ-RL finds applications in various electronic devices where voltage monitoring and reset functions are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing data corruption during power fluctuations.
2. Industrial Control Systems: Providing reliable reset signals to maintain system integrity.
3. Battery-Powered Devices: Protecting against undervoltage conditions and preserving battery life.
