ADM811TARTZ-REEL

Supervisors Overview

The ADM811TARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 3.08 V. The device provides an active low reset output with a typical reset delay time of 560 ms. It supports manual reset functionality via a dedicated input pin, allowing users to trigger a system reset independently of power conditions. The component is housed in a compact SOT-143-4 surface-mount package and is designed for reliable performance across the industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Manual reset capability allows independent system control
• Active low push-pull reset output
• Compact SOT-143-4 surface mount packaging

Supervisors Applications

• Monitoring 3.0 V power supplies
• Microprocessor reset generation
• Battery backup systems

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as 'REEL' indicates tape-and-reel packaging which may differ from cut-tape or tube variants. Confirm the specific threshold voltage variant matches the design requirement, as the ADM811 family includes multiple options. Check current availability status directly with the manufacturer or authorized distributors, as supply constraints may apply to this specific reel configuration.

Supervisors Selection Notes

Select this component when a precise 3.08 V monitoring threshold is required for standard logic families. Ensure the application benefits from the manual reset feature for diagnostic purposes. Verify that the 560 ms reset delay aligns with the target microcontroller's startup timing requirements. Consider the SOT-143 footprint constraints during PCB layout planning.

Supervisors Part Context

This part belongs to the ADM811/ADM812 series of voltage supervisors, which serve as successors to the MAX811/MAX812 lines. The series is characterized by low power consumption and precision monitoring capabilities for common voltage rails. The TARTZ suffix typically denotes a specific temperature grade and packaging type within the Analog Devices portfolio.

Supervisors Replacement Considerations

Publicly confirmed substitutes include APX811-31UG-7 from Diodes Incorporated and MIC811RUY-TR from Microchip Technology.
