ADM811SART-REEL7

Supervisors Overview

The ADM811SART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and supports threshold voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The device features a push-pull output type and includes manual reset functionality. It provides a fixed reset delay time of 560 ms to ensure stable power-up sequencing. The component is housed in an SOT-143-4 surface-mount package and is rated for operation across a temperature range starting from -40 °C.

Supervisors Feature Summary

• Manual reset capability allows external triggering of the reset signal independent of voltage thresholds.
• Push-pull output structure provides active drive capability for reliable logic interfacing.
• Fixed reset delay ensures consistent timing during power-up sequences.

Supervisors Applications

• Microprocessor system power supervision
• Battery-powered equipment voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel configuration against current manufacturer documentation, as availability may vary. Confirm RoHS compliance status and lead times with authorized distributors prior to ordering. Ensure the selected threshold voltage matches the target supply rail requirements for the application design.

Supervisors Selection Notes

Select this component when a simple supervisor with manual reset is required for low-voltage systems. Compare threshold options (2.5 V, 3 V, 3.3 V, 5 V) against the monitored rail. Consider the 560 ms delay for system startup timing. Verify SOT-143-4 footprint compatibility with PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM811 series of microprocessor supervisory circuits from Analog Devices. The series offers various threshold voltages and packages to support diverse embedded system designs. The ART suffix indicates a specific tape-and-reel packaging variant suitable for automated assembly processes.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ADM811SARTZ-REEL and ADM811SARTZ-REEL7 from Analog Devices. Other manufacturers offer functionally similar devices such as STM811SW16F, MIC811SUY-TR, and APX811-29UG-7, though pinouts and electrical characteristics should be verified.
