ADM690AARNZ-REEL

Supervisors Overview

The ADM690AARNZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.65 V. The device provides an open collector output type and includes a watchdog timer function along with battery backup switchover capabilities. It has a reset delay time of 200 ms and consumes 100 uA of operating current. The component supports power failure detection and is housed in an SOIC-8 package, suitable for surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides battery backup switchover functionality
• Detects power failure conditions automatically

Supervisors Applications

• Microprocessor system supervision
• Battery-powered device power management
• Embedded system voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation as requirements may vary by production batch. Ensure the open-collector output configuration matches the target circuit design requirements before integration.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for CMOS process ICs. Consider the 200 ms reset delay and open-collector output characteristics against application timing needs. Evaluate the SOIC-8 package constraints for PCB layout space availability.
