ADM706PARZ

Supervisors Overview

The ADM706PARZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supplies and battery levels in systems operating up to 5.5 V. It features a precision voltage monitor with a threshold of 4.40 V, ensuring valid reset signals down to 1 V supply voltage. The device includes an independent watchdog timer with a 1.60-second timeout and a debounced manual reset input. It operates with a quiescent current of 190 μA and provides a push-pull active low reset output. The component supports a reset pulse width of 200 ms and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated independent watchdog timer with fixed timeout for system reliability
• Precision voltage monitoring with guaranteed reset validity at low supply voltages
• Debounced manual reset input compatible with TTL/CMOS logic levels
• Active low push-pull reset output for direct microprocessor interface

Supervisors Applications

• Microprocessor system power supervision
• Critical microprocessor supply monitoring
• Controllers and intelligent instruments
• Computers requiring reliable reset generation

Supervisors Procurement Notes

Verify the specific suffix 'P' indicates the plastic DIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the part number matches the exact electrical specifications required for your design, particularly the 4.40 V threshold. Check for obsolescence notices as this series may have replacement recommendations from Analog Devices.

Supervisors Selection Notes

Select the ADM706PARZ when a 4.40 V threshold is required for 5 V supply monitoring. Choose this package type if through-hole mounting is necessary for the application. Consider the 190 μA quiescent current for power-sensitive designs. Verify that the 1.60 s watchdog timeout meets the system's timing requirements compared to other variants in the ADM706 family.

Supervisors Part Context

The ADM706PARZ belongs to the ADM705/ADM706/ADM707/ADM708 family of low-cost microprocessor supervisory circuits. These devices are engineered to monitor 5 V power supplies and batteries while also tracking microprocessor activity. The family offers various threshold voltages and output polarities to suit different system architectures, serving as a superior upgrade for legacy MAX705-MAX708 components.
