ADM695ARZ

Supervisors Overview

The ADM695ARZ is a CMOS supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides reset output signals when supply voltages exceed specified thresholds. The device operates within a power supply range of 4.75 V to 5.5 V, featuring a threshold voltage of 4.65 V and an overvoltage threshold of 4.73 V. Key electrical parameters include a reset delay time of 200 ms, a maximum power dissipation of 600 mW, and a typical operating supply current of 1.95 mA. It supports a watchdog timer and battery backup switching functions, with an open-drain output type and chip enable signal capability.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports battery backup switching functionality
• Features a manual reset pin for user control
• Provides open-drain reset output signals

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in industrial equipment
• Battery backup switching circuits

Supervisors Procurement Notes

Verify the specific suffix (ARZ) against official Analog Devices documentation to confirm package type and temperature range. Confirm RoHS compliance status through the manufacturer's datasheet or environmental declaration. Check for any recent product change notices regarding availability or manufacturing location changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for 5 V systems. Ensure the application utilizes a 5V CMOS process compatible logic family. Verify that the 200 ms reset delay meets the timing requirements of the target microcontroller or processor. Consider the SOIC-16 package constraints for PCB layout and thermal management.

Supervisors Part Context

The ADM695ARZ belongs to the ADM691/ADM695/ADM696 series of supervisory circuits from Analog Devices. These devices are designed for low-cost, high-reliability voltage monitoring applications. The ARZ suffix typically denotes a lead-free, RoHS-compliant version in a specific surface-mount package, distinguishing it from older non-compliant variants.

Supervisors Replacement Considerations

Direct replacements may include other parts from the ADM69x series with matching threshold voltages. Verify pinout compatibility and electrical specifications such as reset delay and supply current before substitution.
