ADM699AR-REEL

Supervisors Overview

The ADM699AR-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., housed in a 16-pin SOIC package. It monitors a single input with a threshold voltage range of 3 V to 5.5 V and features a push-pull output type. The device includes an integrated watchdog timer and has a reset delay time of 280 ms. It operates without manual reset or battery backup switching capabilities. The maximum power supply voltage is 5.5 V, with a working supply current of 1.95 mA. The overvoltage threshold is specified at 4.73 V, and the power dissipation is 375 mW. The component supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides push-pull output configuration for direct logic interfacing
• Supports extended industrial temperature operation

Supervisors Applications

• Power-on reset generation in embedded systems
• Watchdog timer implementation for microcontroller supervision
• Voltage monitoring in CMOS process circuits

Supervisors Procurement Notes

Verify the specific suffix REEL indicates reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary. Check lead times due to potential lifecycle changes. Ensure the SOIC-16 footprint matches the target PCB design. Validate that the 280 ms reset delay meets system timing requirements.

Supervisors Selection Notes

Select this component for applications requiring a dedicated watchdog function alongside voltage supervision. Compare the 280 ms reset delay against other series options if faster response is needed. Consider the push-pull output drive capability versus open-drain alternatives. Verify the 3 V to 5.5 V threshold range covers the target supply rail accurately.
