ADM823TYRJZ-R7

Supervisors Overview

The ADM823TYRJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., housed in a SOT-23-5 surface-mount package. It functions as a voltage supervisor with an integrated watchdog timer and manual reset capability. The device monitors a single input line and features an active low, push-pull output. It operates within a supply voltage range of up to 5.5 V and maintains accuracy within 2.5%. The component supports a wide operating temperature range from -40°C to +125°C and draws a typical supply current of 20 µA.

Supervisors Feature Summary

• Integrated watchdog timer for system monitoring
• Manual reset input functionality
• Active low push-pull output configuration

Supervisors Applications

• Microprocessor system supervision
• Watchdog timer implementation
• Voltage monitoring circuits

Supervisors Procurement Notes

Verify the specific threshold voltage variant required for the application, as the series includes options such as 1.58 V and 3.08 V. Confirm that the SOT-23-5 package aligns with the PCB footprint design. Ensure the selected part number suffix corresponds to the exact reset delay and accuracy specifications needed for the target environment.

Supervisors Selection Notes

Select this component when a compact supervisory solution with built-in watchdog protection is required. The low quiescent current makes it suitable for battery-operated systems. Verify that the monitored voltage level matches the available threshold options within the ADM823 series. Consider the thermal performance requirements given the extended industrial temperature range.

Supervisors Part Context

This part belongs to the ADM823 family of supervisory circuits from Analog Devices. These devices are designed to provide reliable power management and system reset functions in embedded applications. The family offers various threshold voltages and packaging options to suit different design constraints while maintaining consistent functional characteristics.

Supervisors Replacement Considerations

Compatible substitutes include other ADM823 variants with matching threshold voltages, such as ADM823VYRJZ-RL7 or ADM823WYRJZ-RL7, provided the pinout and package remain identical.
