ADM809JARTZ-REEL7

Supervisors Overview

The ADM809JARTZ-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 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 switching capabilities. The component draws a working supply current of 60 uA and supports an overvoltage threshold of 4.06 V. It is housed in an SOT-23-3 package and operates across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides voltage supervision for a single input channel with a fixed threshold.
• Delivers a push-pull reset signal with a specified delay duration.
• Operates without requiring manual reset inputs or external watchdog timers.

Supervisors Applications

• Monitoring power supply voltages in embedded systems
• Ensuring system stability in industrial control environments
• Protecting microcontroller resets in automotive electronics

Supervisors Procurement Notes

Verify the specific suffix JARTZ corresponds to the required threshold voltage and package configuration before ordering. Confirm that the absence of manual reset and watchdog features aligns with the target application design requirements. Ensure compatibility with the SOT-23-3 footprint during PCB layout validation.

Supervisors Selection Notes

Select this component when a fixed 4 V threshold is appropriate for the monitored rail. Consider the 60 uA supply current for low-power designs. Verify that the 240 ms reset delay meets the system startup timing constraints. Ensure the operating temperature range covers the intended environmental conditions.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It shares the same package and basic functionality as other variants in the family but differs in threshold voltage specifications. The REEL7 designation indicates tape and reel packaging for automated assembly processes.

Supervisors Replacement Considerations

ADM809LARTZ-REEL7 offers a different threshold voltage (4.63 V) while maintaining similar package and feature sets. Other ADM809 variants may provide alternative thresholds suitable for different supply rail monitoring needs.
