ADM811ZART-REEL7

Supervisors Overview

The ADM811ZART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-channel power supply voltages. It operates within a maximum supply voltage of 5.5 V and features an active low output type with manual reset capability. The device includes a reset delay time of 560 ms and maintains an accuracy of 1.5%. It functions reliably across a temperature range from -40°C to +85°C, drawing a typical operating supply current of 15 µA. Packaged in an SOT-143-4 format on a reel, it serves as a robust solution for microprocessor supervision applications requiring precise threshold detection.

Supervisors Feature Summary

• Manual reset input allows system recovery from undetected states
• Active low output provides clear status indication
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Microprocessor supervision circuits
• Voltage monitoring for standard PSU rails
• System reset generation in embedded devices

Supervisors Procurement Notes

Verify the specific suffix ZART against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with your board's thermal and electrical requirements before finalizing procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance details directly from the latest datasheet revision.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset functionality is required. Consider the 560 ms reset delay and 1.5% accuracy for timing-sensitive designs. Evaluate the SOT-143-4 package constraints against available PCB space. Compare operating current and voltage thresholds against other ADM811 variants to ensure optimal performance for the specific application voltage.

Supervisors Part Context

This part belongs to the ADM811 series of voltage supervisors from Analog Devices. These devices are engineered to monitor six different voltages, allowing reduction relative to standard PSU voltages. They serve as reliable upgrades for legacy MAX811/MAX812 designs, offering rated performance across the entire industrial temperature range while maintaining low power characteristics.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers include ADM811SARTZ-REEL7 and ADM811LARTZ-REEL7. Verify pinout and threshold voltage compatibility before substitution.
