ADM706SARZ-REEL

Supervisors Overview

The ADM706SARZ-REEL is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.0 V to 5.5 V and features a typical reset threshold voltage of 2.93 V, with minimum and maximum limits of 2.85 V and 3.0 V respectively. The device includes an independent watchdog timer with a 1.6-second timeout period and a manual reset input. Key electrical parameters include a reset delay time of 200 ms, a maximum power dissipation of 470 mW, and a working supply current ranging from 100 µA to 250 µA depending on specific conditions. It utilizes a push-pull output driver and is housed in an SOIC-8 package.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a dedicated low-battery warning threshold for comprehensive power supervision.
• Includes an independent watchdog timer with a fixed timeout interval to detect software malfunctions or system hangs.
• Features a debounced manual reset input compatible with TTL and CMOS logic levels for external control.

Supervisors Applications

• Microprocessor system power monitoring
• Computer hardware reset generation
• Controller unit supervision
• Smart instrument power management

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure the reel packaging matches production requirements. Cross-reference the datasheet revision date to validate parameter accuracy. Confirm RoHS compliance status through authorized channels. Validate that the component meets the specific temperature range requirements for the intended industrial application environment.

Supervisors Selection Notes

Select this component when a single-supervision channel with integrated watchdog functionality is required. The 2.93 V threshold suits standard 3.3 V logic systems. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate the 1.6-second watchdog timeout against the processor's clock cycle to ensure reliable fault detection without false triggers during normal operation cycles.

Supervisors Part Context

This part belongs to the ADM706 series of microprocessor supervisors. The series provides various threshold voltages and package options including DIP and SOIC formats. The SARZ suffix indicates a lead-free, halogen-free variant compliant with environmental standards. The REEL designation specifies tape-and-reel packaging for automated placement processes.

Supervisors Replacement Considerations

ADM706ARZ-REEL7 offers a higher threshold voltage of 4.4 V. ADM706SAN is a PDIP version with different mounting requirements. ADM708SARZ provides active high/low selectable outputs. Verify pinout and threshold voltage compatibility before substitution.
