ADM809LART-REEL

Supervisors Overview

The ADM809LART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switch capabilities. The component supports surface-mount installation in an SOT-23-3 package and maintains operation across a temperature range from -40 C to +125 C while consuming 60 uA of working power current.

Supervisors Feature Summary

• Provides voltage supervision for a single input channel with push-pull output configuration
• Operates reliably across an extended industrial temperature range from -40 C to +125 C
• Features high accuracy threshold detection with low quiescent current consumption

Supervisors Applications

• Monitoring power rails in embedded systems requiring precise voltage supervision
• Industrial control applications operating within extreme temperature environments
• Consumer electronics utilizing surface-mount technology for compact designs

Supervisors Procurement Notes

Verify the exact suffix designation when sourcing, as availability varies significantly between specific variants like the LARTZ version. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as some listings indicate detailed verification requirements. Ensure the selected reel or cut tape format matches your automated assembly equipment specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-channel supervision. Consider the SOT-23-3 package constraints for board space limitations. Evaluate the 240 ms reset delay against system startup timing requirements. Verify that the absence of manual reset and watchdog features aligns with the overall system safety architecture design.
