ADM1812-10ART-RL7

Supervisors Overview

The ADM1812-10ART-RL7 is a supervisory circuit manufactured by Analog Devices Inc. It functions as a microprocessor reset generator designed to monitor voltage levels and assert a reset signal when power supply conditions fall outside specified thresholds. The device operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 4.35 V. It provides a reset delay time of 250 ms to ensure stable system initialization. The component utilizes an open-drain output configuration and is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained electronic designs.

Supervisors Feature Summary

• Monitors single input voltage with a fixed 4.35 V threshold
• Provides 250 ms reset delay for stable power-up sequencing
• Features open-drain output compatible with various logic families

Supervisors Applications

• Microprocessor reset generation
• Voltage supervision in embedded systems
• Power management circuits requiring reliable reset signals

Supervisors Procurement Notes

Verify the exact suffix (ART vs ARTZ) against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance. Confirm availability through authorized distributors as supply status may vary. Ensure the SOT-23-3 package footprint matches your PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.35 V monitoring threshold is required for systems powered by 5 V rails. The open-drain output allows for flexible pull-up resistor selection to match system logic levels. Consider the 250 ms delay duration to ensure it aligns with the startup requirements of the controlled microprocessor or memory devices.

Supervisors Part Context

This part belongs to the ADM1812 series of supervisory circuits from Analog Devices. The series includes variants with different threshold voltages and output types. The 'ART' designation indicates the specific package type and tape-and-reel packaging format used for automated assembly processes.

Supervisors Replacement Considerations

Check for ADM1812-10AKS-RL7 if a push-pull output is preferred instead of open-drain. Verify functional compatibility with other ADM181x series parts having similar threshold voltages and reset delays.
