ADM693AAN

Supervisors Overview

The ADM693AAN is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and monitors a single input with a threshold voltage of 4.4 V. The device features an open-drain output type and includes a watchdog timer and battery backup switch functionality. It provides power-fail detection and has a reset delay time of 70 ms. The component is housed in a 16-pin PDIP package, supports manual reset, and functions within an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch capability for seamless power transitions
• Power-fail detection with programmable clock output
• Manual reset input for direct user control

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment power management
• Industrial control system monitoring

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides genuine components with traceable manufacturing data. Cross-reference the part number with current datasheets to validate availability status and any potential obsolescence notices before finalizing orders.

Supervisors Selection Notes

Select this component when a 5V CMOS supervisory circuit with integrated watchdog and manual reset is required. Consider the PDIP package for through-hole mounting requirements. Verify that the 70 ms reset delay and 4.4 V threshold align with the target system's timing and voltage specifications. Confirm compatibility with the intended operating temperature range.

Supervisors Part Context

The ADM693AAN belongs to the ADM693A series of voltage supervisory circuits from Analog Devices. This family is designed for microprocessor applications requiring reliable power monitoring. The 'AN' suffix typically denotes the 16-pin PDIP package variant, distinguishing it from surface-mount options like the ARZ or AARWZ series.

Supervisors Replacement Considerations

The MAX693AESE+ is a documented substitute within the Analog Devices portfolio. Verify pin compatibility and electrical parameter alignment before substitution.
