ADM698AN

Supervisors Overview

The ADM698AN is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.65 V with an overvoltage threshold of 4.73 V. The device provides a push-pull output type and includes a built-in watchdog timer for system protection. It has a reset delay time of 200 ms and does not support manual reset or battery backup switching. The component functions without a chip enable signal and lacks power failure detection capabilities. It draws a typical operating supply current of 1.95 mA and dissipates up to 500 mW of power. The ADM698AN is rated for operation between -40°C and +85°C and is housed in a PDIP-8 package.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system fault recovery
• Provides push-pull output configuration for direct logic interfacing
• Monitors single input voltage against defined threshold levels

Supervisors Applications

• Power supply supervision in industrial control systems
• Watchdog timer implementation in embedded microcontroller circuits
• Voltage monitoring in CMOS-based digital logic systems

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or special order requirements through authorized distributors. Confirm RoHS compliance details and specific manufacturing lot dates prior to procurement. Ensure the PDIP-8 through-hole package aligns with existing PCB footprint designs. Validate that the 4.65 V threshold meets the specific system voltage monitoring requirements.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with integrated watchdog functionality is required for CMOS systems. The fixed 4.65 V threshold suits standard 5 V logic applications. Consider the PDIP-8 package if through-hole assembly is mandated. Note the absence of manual reset and battery backup features; alternative parts are needed if these functions are critical to the design.
