ADM8693ARUZ

Supervisors Overview

The ADM8693ARUZ is a single-channel voltage supervisor IC manufactured by Analog Devices Inc., housed in a 16-TSSOP surface-mount package. It monitors a single supply voltage with a threshold of 4.4V and provides push-pull outputs for active-high or active-low reset signals. The device features a minimum reset timeout of 35ms and operates within a temperature range of -40°C to +85°C. Designed for backup battery circuit applications, it supports a maximum operating supply voltage of 5.5V.

Supervisors Feature Summary

• Provides hardware reset signaling for microprocessor systems through configurable active-high or active-low outputs.
• Monitors a single power rail against a fixed 4.4V threshold to detect under-voltage conditions.
• Ensures system stability during power-up and power-down transitions via a guaranteed minimum reset delay.

Supervisors Applications

• Backup battery circuit monitoring
• Microprocessor supervisory circuits
• Power management systems requiring voltage threshold detection

Supervisors Procurement Notes

Verify the specific suffix 'ARUZ' corresponds to the 16-TSSOP package variant. Confirm that the component status is acceptable for new designs, as documentation indicates this product may be discontinued. Ensure the required reset polarity (high/low) matches the application needs, as the device supports both configurations.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 4.4V threshold is required. The 16-TSSOP package suits space-constrained surface-mount designs. Consider the 35ms minimum timeout for systems requiring extended power stabilization periods. Verify compatibility with the target logic levels for the push-pull output drivers.

Supervisors Part Context

This part belongs to the ADM869x family of supervisory circuits from Analog Devices. These devices are engineered for reliable power management in embedded systems. The ADM8693 specifically targets applications needing precise voltage monitoring without external components, integrating threshold detection and timing functions into a compact footprint.
