ADM6319B25ARJZ-R7

Supervisors Overview

The ADM6319B25ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for power supply management in single-channel applications. It operates within an input voltage range of up to 5.5 V and features a fixed reset threshold voltage of 2.5 V, with an accuracy of 2.5%. The device draws a typical quiescent current of 20 uA and provides a push-pull active low output. It includes a manual reset input but lacks a watchdog timer function. The component supports a reset delay time of 200 ms and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a manual reset input for user-initiated system control alongside automatic voltage monitoring capabilities.
• Provides a push-pull active low reset output stage suitable for direct interfacing with digital logic inputs.
• Ensures power supply glitch immunity to prevent false triggering during transient voltage events.

Supervisors Applications

• Microprocessor systems requiring reliable power-on reset sequences
• Battery-powered devices needing low standby current consumption
• Industrial control units operating within extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the B25 designation corresponds to the 2.5 V threshold variant. Check current availability status as distribution may be limited. Ensure compatibility with existing PCB footprint designs utilizing the SOT-23-5 package. Validate RoHS compliance documentation for regulatory requirements.

Supervisors Selection Notes

Choose this component when a fixed 2.5 V threshold is required without adjustable options. Select for applications prioritizing low power consumption over watchdog functionality. Consider the push-pull output capability if driving loads directly without external pull-ups. Evaluate the 200 ms reset delay against system startup timing requirements.

Supervisors Part Context

This part belongs to the ADM6319 series of supervisory circuits from Analog Devices. It shares the family's core architecture but differs in its specific reset threshold voltage setting. The series offers multiple threshold options ranging from 2.5 V to 5 V in increments. It utilizes the standard 5-lead SOT-23 package common to the ADM631x line.

Supervisors Replacement Considerations

ADM6319B25ARJZ-RL7 is a confirmed substitute with identical electrical specifications and pinout configuration. Verify that any alternative parts maintain the same push-pull output type and manual reset input presence.
