ADM706RAR-REEL7

Supervisors Overview

The ADM706RAR-REEL7 is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies. It features a precision voltage monitor with a typical threshold of 2.93 V and an independent watchdog timer with a 1.6-second timeout. The device provides an active low push-pull reset output and includes a debounced manual reset input. Operating from a supply voltage range up to 5.5 V, it draws a quiescent current of 100 μA. The component is housed in an 8-pin SOIC package and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a fixed threshold for reliable power supervision
• Includes an independent watchdog timer with a 1.6-second timeout interval
• Features a debounced manual reset input for user-initiated system control

Supervisors Applications

• Microprocessor systems requiring critical voltage supervision
• Battery-operated portable instruments
• Controllers and intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix REEL7 against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the active low output configuration matches the design requirements. Confirm RoHS compliance status as indicated in the latest documentation before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for 3 V or 3.3 V rail monitoring. The integrated watchdog timer simplifies design by removing external timing components. Verify that the active low output polarity aligns with the target microprocessor reset pin logic.
