ADM809TARTZ-REEL7

The ADM809TARTZ-REEL7 is a supervisory circuit IC manufactured by Analog Devices Inc./Maxim Integrated. It is specifically designed to monitor the power supply voltage of microcontrollers, microprocessors, and other embedded systems, ensuring reliable system operation by providing reset signals during power-up, power-down, and brownout conditions. This supervisory circuit IC offers essential functionality for maintaining system integrity and preventing erratic behavior or data corruption in critical applications.

Key Features:

• Voltage Monitoring: The ADM809TARTZ-REEL7 continuously monitors the power supply voltage of the target system, ensuring that it remains within safe operating limits. It compares the monitored voltage against a predefined threshold and generates a reset signal when the voltage falls below the specified level.

• Precision Voltage Threshold: The supervisory circuit IC features a precise voltage threshold (typically 3.0V) that determines when the reset signal is triggered. This threshold can be set to accommodate different power supply voltages and system requirements, providing flexibility in voltage monitoring.

• Reset Output Options: Depending on the application requirements, the ADM809TARTZ-REEL7 offers different reset output configurations, including active-high and active-low reset signals. These options allow for compatibility with a wide range of microcontrollers and system architectures.

• Adjustable Reset Timeout Period: The IC allows for the adjustment of the reset timeout period, which determines the duration of the reset pulse generated after the voltage returns to a valid operating range. This feature ensures proper system initialization and stabilization before normal operation resumes.

• Manual Reset Input: In addition to automatic reset generation, the ADM809TARTZ-REEL7 includes a manual reset input (MR), allowing external devices or users to initiate a system reset when necessary. This feature enhances system flexibility and facilitates diagnostic or recovery procedures.

• Low Quiescent Current: Designed for low power consumption, the supervisory circuit IC consumes minimal quiescent current during operation, conserving energy and extending battery life in portable or battery-powered applications.

• Wide Operating Temperature Range: With its wide operating temperature range, the ADM809TARTZ-REEL7 is suitable for use in various environmental conditions, including industrial, automotive, and consumer electronics applications.

• Small Package: Housed in a compact surface-mount package (SOT-23), the IC offers a small footprint and simplified PCB layout, making it ideal for space-constrained designs or applications with limited board space.
