ADM825RYRJZ-R7

Supervisors Overview

The ADM825RYRJZ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.08 V with an accuracy of 2.5%. The device provides a push-pull output and includes manual reset functionality, though it lacks a watchdog timer or battery backup switch. It exhibits a reset delay time of 280 ms and draws a typical operating supply current of 24 uA. The component supports overvoltage detection at a threshold of 3.11 V and functions reliably across an extended temperature range from -40 C to +125 C. It is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates manual reset capability for user-initiated system recovery without requiring external components.
• Provides precise voltage monitoring with defined threshold and overvoltage detection levels for reliable supervision.
• Features low quiescent current consumption suitable for power-sensitive applications.
• Delivers a push-pull output stage capable of driving downstream logic interfaces directly.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing robust voltage supervision
• Communication equipment ensuring stable operation under varying line conditions

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation prior to integration. Ensure the SOT-23-5 footprint matches your PCB layout constraints. Check for any regional distribution restrictions that may affect availability. Validate the manufacturer part number against the latest datasheet revision to ensure functional equivalence.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset is required. Consider the 2.5% accuracy and 280 ms delay for timing-critical designs. Evaluate the 24 uA supply current against total system power budgets. Ensure the 5.5 V maximum input rating aligns with the target supply rail. Verify thermal performance requirements against the specified operating temperature range.

Supervisors Part Context

This part belongs to the ADM825 series of supervisory circuits from Analog Devices. The series focuses on providing essential power management functions in a minimal footprint. These devices are engineered for applications where space is limited but reliability is paramount. The family typically offers various threshold options to accommodate different voltage rails.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout configuration and electrical specifications. Verify compatibility with existing board layouts before implementation.
