ADM809RART-REEL

Supervisors Overview

The ADM809RART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It consumes 60 uA of operating current and lacks manual reset, watchdog timer, or battery backup switch functions. The component supports surface mount installation in an SOT-23-3 package and functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides voltage supervision with a fixed threshold for reliable power monitoring
• Features a push-pull output stage for direct interface with digital logic
• Operates with low quiescent current consumption suitable for power-sensitive designs

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix and packaging configuration against official Analog Devices documentation to ensure compatibility with design requirements. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Cross-reference the exact part number with the manufacturer's latest datasheet to validate electrical parameters and package dimensions before procurement.

Supervisors Selection Notes

Select this component when a fixed threshold voltage supervisor is required without additional features like watchdog timers or manual resets. Ensure the 2.63 V threshold aligns with the monitored rail voltage. Verify that the SOT-23-3 package fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It is specifically configured with an R suffix indicating the 2.63 V threshold variant. The ARTZ designation typically denotes the RoHS-compliant version in the SOT-23-3 package. This series is designed for cost-effective power management solutions requiring basic reset functionality.

Supervisors Replacement Considerations

Check for ADM809RARTZ-REEL7 as a potential RoHS-compliant alternative with identical electrical characteristics. Verify package compatibility and pinout alignment before substitution. Consult official replacement guides for any functional differences in threshold voltages or timing parameters.
