ADM6823VYRJZ-RL7

Supervisors Overview

The ADM6823VYRJZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., featuring an integrated watchdog timer and manual reset input. It operates within a supply voltage range up to 5.5 V and monitors a single input channel with a threshold voltage of 1.58 V. The device provides an active low, push-pull reset output with a reset delay time of 200 ms and an overvoltage threshold of 1.62 V. It consumes 10 uA of operating current and maintains accuracy within 2.5%. The component is housed in a SOT-23-5 package and functions reliably across temperatures from -40 C to +125 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside voltage supervision capabilities
• Includes a manual reset input allowing direct user control over the reset state
• Delivers a push-pull active-low reset output ensuring robust signal driving capability

Supervisors Applications

• Embedded systems requiring precise low-voltage monitoring
• Microcontroller power supply management circuits
• Industrial control units needing watchdog protection

Supervisors Procurement Notes

Verify end-of-life status as the manufacturer indicates this part is obsolete and will be discontinued. Confirm availability through authorized distributors or secondary markets, as standard supply channels may not stock this item. Ensure compatibility with existing designs before sourcing due to potential obsolescence constraints.

Supervisors Selection Notes

Select this component when a fixed 1.58 V threshold is required for single-channel supervision. The inclusion of both a watchdog timer and manual reset makes it suitable for complex systems needing multiple reset sources. Consider the SOT-23-5 package size for space-constrained PCB layouts and verify temperature range requirements against the specified -40 C to +125 C operational limits.

Supervisors Part Context

This part belongs to the ADM6823 series of low voltage supervisory circuits. It shares functional similarities with other members like the ADM6824 but differs in specific threshold voltages. The series is designed for compact applications using the 5-lead SOT-23 package, offering precision monitoring with low power consumption characteristics typical of Analog Devices' power management portfolio.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components must be selected based on matching electrical parameters such as threshold voltage, package type, and functionality rather than direct cross-references.
