ADM811ZARTZ-REEL

Supervisors Overview

The ADM811ZARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor monitoring applications. It features an active low output and manual reset capability within a SOT-143-4 surface-mount package. The device monitors a single input with a threshold voltage of 2.32 V and an overvoltage threshold of 2.35 V. It operates on supply voltages up to a maximum of 5.5 V, with a minimum operating voltage of 1.2 V. Key electrical parameters include a reset delay time of 560 ms, accuracy of 1.5%, and a working supply current of 15 uA. The component supports an operating temperature range from -40 C to +85 C and has a power dissipation rating of 200 mW.

Supervisors Feature Summary

• Provides voltage supervision with active low output signaling for system reset control.
• Includes manual reset functionality allowing user-initiated system restarts.
• Features high accuracy voltage monitoring with specified threshold tolerances.
• Operates with low power consumption suitable for battery-backed or energy-efficient designs.

Supervisors Applications

• Microprocessor supervisor ICs in embedded systems
• Voltage monitoring for portable electronic devices
• System reset generation in industrial control circuits

Supervisors Procurement Notes

Verify the specific suffix ZARTZ-REEL against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure the threshold voltage variant matches the design requirement of 2.32 V. Check RoHS compliance status and lead-free soldering compatibility for assembly processes. Confirm availability through authorized distributors as stock levels may vary. Validate that the SOT-143-4 package dimensions align with PCB footprint constraints.

Supervisors Selection Notes

Select this component when a precise 2.32 V threshold is required for voltage supervision. Consider the 15 uA supply current for low-power applications. The manual reset feature is essential if user intervention is needed for system recovery. Ensure the 5.5 V maximum supply voltage accommodates the highest expected rail voltage. Verify that the 560 ms reset delay meets the timing requirements of the monitored processor.
