ADM809LARTZ-REEL7 - Supervisory Circuit from Analog Devices Inc.

The ADM809LARTZ-REEL7 is a highly reliable supervisory circuit designed and manufactured by Analog Devices Inc., an industry leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This component is specifically engineered to monitor power supply voltages in microprocessor systems, helping to ensure proper system operation through reset and monitoring functions.

Encased in a compact SOT-23 package, the ADM809LARTZ-REEL7 is an ideal solution for space-constrained applications. It is designed to maintain system integrity by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the microprocessor and associated circuitry reset cleanly during power-up, power-down, or brown-out conditions.

The device features a precision voltage monitor with a factory-trimmed reset threshold voltage. When VCC falls below this threshold, the reset output becomes active (low) and remains active for a minimum reset timeout period after VCC rises above the threshold, providing a predictable reset de-assertion. This timeout period prevents the system from restarting until the power supply has stabilized, an essential feature for preventing system errors and data corruption.

Furthermore, the ADM809LARTZ-REEL7 is designed for low power consumption, making it suitable for portable and battery-powered applications. It operates over a wide range of supply voltages and temperature ranges, ensuring reliable performance under various conditions. The device is also available in a tape and reel format (REEL7), which facilitates automated manufacturing processes, making it convenient for mass production assembly lines.

Key features of the ADM809LARTZ-REEL7 include:

• Low power consumption
• Factory-trimmed precision voltage monitor
• Active-low reset output
• Minimum reset timeout period
• Wide operating voltage range
• Operational temperature range suitable for commercial applications
• Compact SOT-23 package
• Automated manufacturing-friendly tape and reel packaging

With its robust design and precision monitoring capabilities, the ADM809LARTZ-REEL7 supervisory circuit from Analog Devices Inc. is an excellent choice for ensuring system stability and reliability in a wide array of electronic applications.
