ADM705AR-REEL7

Supervisors Overview

The ADM705AR-REEL7 is a microprocessor supervisory circuit from Analog Devices Inc., designed for monitoring 5V power supplies. It features a precision voltage threshold of 4.65V and a minimum reset timeout of 160ms with a 200ms pulse width. The device operates within a -40°C to +85°C temperature range and draws only 190μA quiescent current. It includes an independent watchdog timer with a 1.60-second timeout and a debounced manual reset input. The part is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Integrated independent watchdog timer for system stability
• Precision supply voltage monitoring at 4.65V threshold
• Debounced TTL/CMOS manual reset input capability
• Low power consumption with 190μA quiescent current

Supervisors Applications

• Microprocessor systems
• Computers
• Controllers
• Intelligent instruments
• Critical microprocessor supply monitoring

Supervisors Procurement Notes

Verify the specific suffix 'REEL7' against official Analog Devices documentation to confirm reel quantity and tape specifications. Confirm RoHS compliance status via the manufacturer's datasheet, as legacy parts may have varying environmental certifications. Ensure the active high/low output configuration matches the base model ADM705 requirements before integration.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer is required alongside voltage supervision. The 4.65V threshold suits standard 5V logic systems. Compare against ADM706/ADM707/ADM708 variants if different thresholds or output polarities are needed. Verify that the 1.60s watchdog timeout aligns with the target microprocessor's service interval requirements.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 series of low-cost microprocessor supervisory circuits. These devices serve as superior upgrades for older MAX705-MAX708 components. The series provides essential power management functions including reset generation and battery backup switching capabilities for embedded applications.

Supervisors Replacement Considerations

Direct replacement options include ADM705ANZ. Similar alternatives from the same family include MAX705CPA+ and MAX705EPA+. Verify pin compatibility and electrical parameters before substituting.
