ADM812SART-REEL7

Supervisors Overview

The ADM812SART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a push-pull output type with manual reset capability. The device monitors a single input and provides threshold voltages of 2.5 V, 3 V, 3.3 V, or 5 V. It includes an overvoltage threshold of 2.98 V and a reset delay time of 560 ms. The component draws a working power supply current of 15 uA and has a maximum power dissipation of 200 mW. It is housed in an SOT-143-4 package and functions within a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Manual reset functionality for controlled system recovery
• Push-pull output configuration for direct interface compatibility
• Low quiescent current consumption for power efficiency

Supervisors Applications

• Microprocessor reset generation
• Battery-powered equipment monitoring
• Portable instrumentation supervision

Supervisors Procurement Notes

Verify the specific suffix and revision level against the manufacturer's official documentation to ensure functional equivalence. Confirm RoHS compliance status as indicated in the latest datasheet. Check for obsolescence notices from Analog Devices prior to finalizing procurement plans. Ensure the ordering information matches the required threshold voltage variant.

Supervisors Selection Notes

Select this component when a manual reset input is required alongside standard voltage supervision. Verify that the available threshold voltages align with the target system rails. Consider the SOT-143-4 package constraints for PCB layout. Evaluate the 560 ms reset delay against the processor startup requirements.

Supervisors Part Context

This part belongs to the ADM812 series of supervisory circuits designed for monitoring power supplies in embedded systems. It complements other variants in the family that may offer different thresholds or packages. The series focuses on providing reliable reset signals for microprocessors and memory devices under varying voltage conditions.

Supervisors Replacement Considerations
