ADM699AN

Supervisors Overview

The ADM699AN is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 4.65 V. The device provides a push-pull output and includes an integrated watchdog timer with a reset delay time of 200 ms. It does not support manual reset or battery backup switching. The component is housed in a PDIP-8 package, suitable for through-hole mounting. It functions without a chip enable signal and has a typical operating supply current of 1.95 mA. The overvoltage threshold is specified at 4.73 V, with a maximum power dissipation of 500 mW.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides a fixed 4.65 V reset threshold for voltage supervision
• Features a push-pull output driver for direct logic interface

Supervisors Applications

• Microprocessor system power monitoring
• Embedded controller reset generation
• Watchdog timer implementation in industrial systems

Supervisors Procurement Notes

Verify the specific suffix 'AN' corresponds to the PDIP-8 through-hole package variant when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Check for obsolescence notices from Analog Devices, as this part number may be subject to limited availability or discontinuation. Ensure the required 4.65 V threshold aligns with the target system's voltage levels before procurement.

Supervisors Selection Notes

Select the ADM699AN when a through-hole PDIP-8 package is required for board layout constraints. This variant is appropriate for applications needing a fixed 4.65 V reset threshold without manual reset functionality. Consider the 200 ms reset delay and 1.95 mA supply current against system power budgets. Verify that the 500 mW power dissipation rating suits the thermal environment of the installation.

Supervisors Part Context

The ADM699AN belongs to the ADM699 series of CMOS supervisory circuits designed for monitoring power supplies in microprocessor-based systems. It combines voltage monitoring with watchdog timer functionality in a single IC. The 'AN' suffix typically denotes the plastic dual in-line package (PDIP) version, distinguishing it from surface-mount variants like the AR. This series is part of Analog Devices' portfolio of power management and supervisory solutions.
