ADM6326-27ARTZ-R7

Supervisors Overview

The ADM6326-27ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-channel power supply voltages. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 2.7 V to detect under-voltage conditions. The device provides a push-pull output stage with an active-low reset signal, ensuring reliable system initialization. It includes a minimum reset timeout of 100 ms to prevent premature assertion during power-up transients. The component supports surface-mount installation in a compact SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signal generation based on monitored input voltage levels
• Features push-pull output stage for robust drive capability
• Includes manual reset input functionality for system control

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-operated systems needing brown-out protection
• Microcontroller-based designs requiring power-on reset signals

Supervisors Procurement Notes

Verify the exact suffix and manufacturer part number against official Analog Devices documentation before procurement. Confirm availability status as distribution channels may list obsolete or discontinued variants. Ensure the ordering information matches the specific threshold voltage and package type required for the design. Cross-reference RoHS compliance and environmental certifications with current datasheets.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for single-supervision applications. Consider the SOT-23-3 package size constraints and the push-pull output characteristics. Evaluate the 100 ms reset timeout against system startup requirements. Verify that the operating temperature range meets the environmental specifications of the target application.

Supervisors Part Context

This part belongs to the ADM6326 series of supervisory circuits from Analog Devices. The series offers various threshold options and package configurations to suit different power management needs. The ADM6326 family is characterized by low quiescent current and high accuracy, making it suitable for battery-powered and space-constrained electronic designs.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ADM6326 series with different threshold voltages if the 2.7 V setting is unsuitable. Verify functional equivalence with other single-channel supervisors offering similar reset timeouts and output types.
