Pin Configuration

ADM1817-10ART-RL7 has three pins arranged as follows:

```

---

| | --| RST | --| GND | --| VCC | |_______| ```

Pin Descriptions: - RST: Active-low reset output - GND: Ground connection - VCC: Supply voltage input

Functional Features

• Voltage Monitoring: ADM1817-10ART-RL7 continuously monitors the supply voltage and asserts the reset output when it falls below the preset threshold.
• Manual Reset Input: It provides a manual reset input pin that allows an external signal to force a reset condition.
• Reset Timeout: The device ensures that the reset output remains asserted for a minimum timeout period of 140ms after the supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Low quiescent current consumption helps in power-sensitive applications.
• Small package size enables space-saving designs.
• Wide supply voltage range allows compatibility with various systems.
• Active-low reset output simplifies interfacing with other components.

Disadvantages

• Fixed voltage threshold may not be suitable for all applications requiring different voltage levels.
• Lack of adjustable timeout period limits flexibility in certain scenarios.

Working Principles

ADM1817-10ART-RL7 operates by comparing the supply voltage with the preset threshold. When the voltage drops below the threshold, the reset output is asserted. It remains asserted for a minimum timeout period after the voltage rises above the threshold. The manual reset input can also force a reset condition.

Application Field Plans

ADM1817-10ART-RL7 finds applications in various fields, including: 1. Battery-powered devices 2. Microcontrollers and microprocessors 3. Industrial control systems 4. Communication equipment 5. Automotive electronics
