ADM8693ANZ

Supervisors Overview

The ADM8693ANZ is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and generate reset signals for microprocessors. It operates within a supply voltage range of 3V to 5.5V, featuring a fixed reset threshold voltage of 4.4V. The device provides a push-pull output with configurable active-high or active-low reset polarity. It includes a minimum reset timeout of 35ms to ensure stable power-up sequencing. The component is housed in a 16-pin PDIP package and supports through-hole mounting. It functions as a single-channel voltage supervisor suitable for embedded systems requiring reliable power management.

Supervisors Feature Summary

• Monitors a single voltage input channel to detect under-voltage conditions
• Provides a programmable reset output polarity for system integration flexibility
• Includes a guaranteed minimum reset timeout duration for stable power-up sequences
• Features a push-pull output stage compatible with standard logic interfaces

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Battery backup circuit supervision
• Industrial control board power management

Supervisors Procurement Notes

Verify the specific revision status of the ADM8693ANZ before procurement, as official documentation indicates this part number may be obsolete or discontinued. Confirm availability through authorized distributors or check for direct replacements if current stock is unavailable. Ensure that the 16-pin PDIP package specification matches your PCB footprint requirements. Cross-reference the datasheet version to confirm the exact reset timeout and threshold parameters, as legacy components may have multiple revisions with subtle electrical differences. Validate RoHS compliance status for your specific manufacturing region requirements.

Supervisors Selection Notes

Select the ADM8693ANZ when a fixed 4.4V threshold is appropriate for the target system's operating voltage. Consider the 16-pin DIP package constraints regarding board space and manual assembly needs. Evaluate the 35ms reset timeout against the microcontroller's required initialization time. Compare alternative parts from the ADM869x family if different thresholds or pin counts are needed. Ensure the push-pull output capability meets the drive requirements of the connected logic circuits without additional buffering.

Supervisors Part Context
