ADM825MYKSZ-R7

Supervisors Overview

The ADM825MYKSZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltages. It features a manual reset function and operates within a voltage range of up to 5.5 V. The device is housed in an SC-70-5 surface-mount package and supports operation temperatures from -40°C to +125°C. It provides a push-pull output with a reset delay time of 280 ms and maintains an accuracy of 2.5%. The part consumes 24 µA of working power current.

Supervisors Feature Summary

• Monitors single power supply input for under-voltage conditions
• Includes manual reset capability for system control
• Provides push-pull output signal for microprocessor interfacing

Supervisors Applications

• Microprocessor system supervision
• Battery-powered device monitoring
• Industrial control system power management

Supervisors Procurement Notes

Verify the specific suffix MYKSZ indicates the SC-70-5 package variant when ordering. Confirm the threshold voltage requirements match the application's monitored rail, as the series includes multiple threshold options. Ensure the manual reset feature aligns with the system design, as this variant lacks a watchdog timer. Check for any regional distribution restrictions or obsolescence notices directly from Analog Devices or authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a low-power supervisor with manual reset is required for systems operating up to 5.5 V. The SC-70-5 package suits space-constrained designs compared to larger SOT-23 variants. Consider the 280 ms reset delay and 2.5% accuracy for timing-sensitive applications. Evaluate if the absence of a watchdog timer meets the safety requirements, opting for other ADM825 variants if automatic timeout reset is necessary.

Supervisors Part Context

The ADM825MYKSZ-R7 belongs to the ADM825 series of supervisory circuits from Analog Devices. This series offers various package options including SOT-23-5 and SC-70-5, with different threshold voltages. The MYKSZ suffix specifically denotes the SC-70-5 package configuration. These devices are part of the broader PMIC portfolio focused on reliable power monitoring for embedded systems.

Supervisors Replacement Considerations

Direct substitutes include other ADM825 variants such as ADM825MYRJ-R7 (SOT-23-5) or ADM825LYRJ-R7, provided the package footprint and threshold voltage are compatible. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
