ADM6823ZYRJZ-RL7

Supervisors Overview

The ADM6823ZYRJZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device incorporates a watchdog timer and manual reset input, providing a reset delay time of 280 ms. It utilizes a push-pull output stage and consumes 20 uA of operating current. The component is housed in a SOT-23-5 package and supports surface mount installation across a temperature range of -40 C to +125 C.

Supervisors Feature Summary

• Integrates a watchdog timer with a 1.6-second timeout period for system fault detection.
• Includes a manual reset input allowing external control over the reset state.
• Features a push-pull active-low reset output stage for robust signal driving.
• Provides guaranteed reset output validity down to a supply voltage of 1 V.

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Portable equipment power management
• Battery-operated devices requiring low quiescent current
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as specified in official documentation. Check for end-of-life indicators or obsolescence notices from Analog Devices prior to procurement planning. Ensure packaging specifications match reel or cut tape requirements for assembly processes.

Supervisors Selection Notes

Select this part when a fixed 2.32 V threshold is required for single-input voltage monitoring. Consider the 280 ms reset delay and 20 uA quiescent current against system timing and power constraints. Verify compatibility with the SOT-23-5 footprint and push-pull output drive capability. Evaluate the absence of battery backup switching if cold-swapping protection is needed.

Supervisors Part Context

This component belongs to the ADM6823 series of low voltage supervisory circuits from Analog Devices. The series offers precision monitoring with multiple threshold options ranging from 1.58 V to 4.63 V. The ADM6823 variant specifically targets applications needing a 2.32 V trip point. It shares common features like watchdog functionality and manual reset inputs across the family while differing in threshold voltages and specific output configurations.

Supervisors Replacement Considerations

ADM6823TYRJZ-RL7: Offers a 3.08 V threshold instead of 2.32 V. ADM6823RYRJZ-RL7: Provides a 2.63 V threshold. Both maintain similar watchdog and manual reset features but differ in reset delay times and accuracy specifications compared to the ZYRJZ variant.
