ADM699ARZ-REEL

Supervisors Overview

The ADM699ARZ-REEL is a CMOS voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 3 V to 5.5 V and features a push-pull output type. The device includes an integrated watchdog timer and provides a reset delay time of 280 ms. It has a single monitored input with a threshold voltage ranging from 3 V to 5.5 V. The component is housed in a SOIC-16 package and is supplied in reel packaging. It functions without manual reset or battery backup switching capabilities.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides push-pull output configuration for direct logic interfacing
• Operates on a single monitored input channel

Supervisors Applications

• CMOS microprocessor power supply supervision
• Watchdog timer implementation in embedded systems
• Voltage monitoring for portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'REEL' against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as indicated in current datasheets, noting that previous records may vary. Ensure the part number matches the exact threshold voltage requirements for your application, as variations exist within the ADM699 series. Cross-reference with authorized distributors for availability, as this component may be subject to limited supply or end-of-life statuses.

Supervisors Selection Notes

Select this component when a CMOS supervisor with an integrated watchdog timer is required for 5V logic systems. The push-pull output eliminates the need for external pull-up resistors, simplifying board design. Verify that the 280 ms reset delay meets the startup timing requirements of the target microprocessor. Consider the SOIC-16 package size constraints during PCB layout planning.

Supervisors Part Context

The ADM699 series belongs to Analog Devices' portfolio of voltage supervisory circuits designed for CMOS applications. These components are engineered to monitor power supply voltages and provide reliable reset signals to protect sensitive digital logic. The ADM699 variant specifically integrates watchdog functionality, distinguishing it from basic supervisors. This family is commonly used in industrial and consumer electronics requiring robust power management.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives such as the ADM699AR (tube) if reel packaging is not strictly required. Verify functional equivalence regarding watchdog timeout periods and reset thresholds before substitution.
