ADM1812-5ARTZ-REEL

Supervisors Overview

The ADM1812-5ARTZ-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 5 V. The device provides a reset signal with a typical delay time of 250 ms. It utilizes an SOT-23-3 surface-mount package and supports push-pull output configurations. The component is designed for single-input monitoring without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Provides automated system reset generation upon power-up or brown-out conditions
• Features a fixed 5 V threshold for precise voltage supervision
• Delivers reset signals via a push-pull output stage

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the exact suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through current datasheets. Ensure compatibility with existing PCB footprints for the SOT-23-3 package before procurement.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for system supervision. The push-pull output allows direct interfacing with logic inputs without external pull-ups. Verify that the 250 ms reset delay meets the target processor's startup timing requirements.

Supervisors Part Context

This part belongs to the ADM1812 series of microprocessor reset circuits from Analog Devices. It is specifically configured for 5 V systems, distinguishing it from other variants in the family that offer different threshold voltages such as 2.5 V, 3 V, or 3.3 V.

Supervisors Replacement Considerations

Check Analog Devices documentation for pin-compatible alternatives within the ADM181x family. Verify if ADM1817 or ADM1811 variants meet specific voltage or output configuration needs.
