ADM811SARTZ-REEL7

The ADM811SARTZ-REEL7 is a voltage supervisor integrated circuit (IC) manufactured by Analog Devices Inc., previously known as Maxim Integrated. This device is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold.

Key Features:

1. Voltage Monitoring: The ADM811SARTZ-REEL7 monitors the supply voltage and ensures that it remains within a specified range. It typically has a fixed threshold voltage, which is critical for ensuring reliable operation of connected devices.

2. Reset Output: When the monitored voltage drops below the threshold, the device generates a reset signal. This output is typically active low, meaning it will pull the reset line low to signal the microcontroller or other digital logic to reset.

3. Debounce Time: The ADM811 includes a built-in delay (or debounce time) to prevent false triggering due to transient voltage dips. This ensures that the reset signal is stable and only activates during genuine power supply issues.

4. Low Power Consumption: The device is designed to operate with minimal power, making it suitable for battery-powered applications. This low quiescent current helps extend battery life in portable devices.

5. Wide Operating Voltage Range: The ADM811SARTZ-REEL7 can operate over a wide range of supply voltages, making it versatile for various applications. It is typically available in different threshold voltage options to suit different system requirements.

6. Compact Package: The device is housed in a small, surface-mount package (often in a SOT-23 or similar form factor), which is ideal for space-constrained applications. This compact design allows for easy integration into printed circuit boards (PCBs).

7. Temperature Range: The ADM811 is designed to operate over a specified temperature range, ensuring reliable performance in various environmental conditions.

Applications:

The ADM811SARTZ-REEL7 is commonly used in a variety of applications, including:

• Microcontroller reset circuits
• Power management systems
• Automotive electronics
• Consumer electronics
• Industrial control systems
• Battery-operated devices

Conclusion:

In summary, the ADM811SARTZ-REEL7 from Analog Devices Inc./Maxim Integrated is a reliable voltage supervisor that provides essential monitoring and reset functionality for digital systems. Its low power consumption, compact size, and wide operating voltage range make it an excellent choice for a variety of electronic applications where power supply stability is critical.
