ADM706TARZ-REEL

Supervisors Overview

The ADM706TARZ-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides power supply monitoring for systems operating within a voltage range of 1.0 V to 5.5 V. The device features a precision voltage monitor with a threshold of 3.08 V and an independent watchdog timer with a timeout period of 1.6 seconds. It generates a reset signal with a pulse width of 200 ms when the supply voltage drops below the specified level or upon power failure. The component includes a debounced manual reset input and operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated independent watchdog timer for monitoring microprocessor activity
• Precision voltage monitor for detecting power-fail or low battery conditions
• Debounced manual reset input compatible with TTL/CMOS logic levels

Supervisors Applications

• Microprocessor systems requiring critical power supervision
• Controllers and intelligent instruments needing reliable reset generation
• Computer systems utilizing 5 V power supplies
• Battery-powered devices requiring low battery warning detection

Supervisors Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the part number matches the exact threshold voltage variant required for the application design. Cross-reference with the latest datasheet revision to validate electrical characteristics and pinout assignments before procurement.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer and precise voltage monitoring are required in a single package. It serves as a direct upgrade for legacy MAX705/MAX708 series applications. Consider the SOIC-8 surface mount package for space-constrained designs. Verify that the 3.08 V threshold aligns with the system's acceptable minimum operating voltage.

Supervisors Part Context

This component belongs to the ADM706 family of microprocessor supervisory circuits from Analog Devices. The family includes variants with different voltage thresholds and output polarities, such as the ADM705, ADM707, and ADM708. These devices are designed to replace older Maxim Integrated parts while offering improved performance and reliability for modern embedded systems.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM706TAR and ADM706TAR-REEL. These variants share identical functional specifications and pinouts. Verify compatibility with existing PCB layouts and ensure the replacement maintains the same watchdog timeout and reset pulse width requirements.
