ADM825RYRJ-R7

Supervisors Overview

The ADM825RYRJ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed reset threshold voltage of 3.08 V with an accuracy of 2.5%. The device provides a push-pull output and includes manual reset functionality, while explicitly lacking watchdog timer or battery backup switching capabilities. It is housed in a compact SOT-23-5 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C. Typical quiescent current consumption is specified at 5 µA, ensuring minimal impact on system power efficiency.

Supervisors Feature Summary

• Provides precise monitoring of single-channel power supplies within the 2.5 V to 5.5 V operating range
• Features a fixed 3.08 V reset threshold with high accuracy for reliable fault detection
• Includes manual reset capability for controlled system recovery without external components
• Delivers low power consumption suitable for battery-operated and portable applications

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-powered devices needing precise voltage supervision
• Industrial control systems operating in extended temperature environments
• Embedded systems requiring manual reset functionality for maintenance

Supervisors Procurement Notes

Verify the exact suffix 'R7' corresponds to reel packaging when sourcing. Confirm the threshold voltage variant matches the required 3.08 V specification, as the ADM825 series offers multiple threshold options. Ensure compatibility with SOT-23-5 footprints during PCB layout. Check regional availability status, as distribution may vary by location. Validate RoHS compliance documentation for regulatory adherence in target markets.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required rather than adjustable options. Consider the SOT-23-5 package size constraints against available board space. Evaluate the absence of watchdog features if automated timeout resets are necessary for the application. Compare quiescent current specifications against other supervisors if ultra-low power is critical. Verify that manual reset integration fits the system design requirements.

Supervisors Part Context

This part belongs to the ADM825 series of voltage supervisors from Analog Devices. The series is characterized by low power consumption and precision monitoring capabilities. Variants differ primarily by reset threshold voltage and packaging style. The ADM825 family targets applications where power efficiency and accurate voltage tracking are essential. Other members share similar architectural features but offer different threshold options.

Supervisors Replacement Considerations

Cross-reference with ADM825RYRJZ-R7 for potential equivalent availability. Verify pinout compatibility between SOT-23-5 variants before substitution. Confirm identical threshold voltage specifications to ensure functional equivalence. Check for any differences in manual reset implementation or output drive characteristics.
