ADM1184ARMZ-REEL7

Supervisors Overview

The ADM1184ARMZ-REEL7 is a quad voltage monitor and sequencer manufactured by Analog Devices Inc. It features four independently adjustable or selectable overvoltage thresholds with an accuracy of 0.8%. The device operates within a supply voltage range up to 5.5 V and draws a typical quiescent current of 24 µA. It provides active high reset outputs via open-drain/open-collector configurations. A fixed reset delay time of 190 ms ensures stable power-up sequencing. The component supports surface mount installation in a 10-MSOP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates four independent voltage monitoring channels with adjustable thresholds for comprehensive power supervision.
• Provides active high reset signals through open-drain or open-collector outputs to interface with various logic families.
• Includes a fixed reset delay timer to manage power-up sequencing and prevent premature system activation.

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage sequence control for complex digital circuits
• Overvoltage protection in industrial instrumentation

Supervisors Procurement Notes

Verify the specific suffix REEL7 confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the 10-MSOP package dimensions align with your PCB footprint design rules. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring with distinct threshold settings. The adjustable threshold capability allows customization for non-standard supply voltages without external resistors. The low quiescent current makes it suitable for battery-powered applications where efficiency is critical. Verify that the open-drain output configuration matches the pull-up requirements of your downstream logic circuitry.

Supervisors Part Context

This part belongs to the ADM1184 series of supervisory circuits designed for multi-voltage systems. It serves as a dedicated power management solution for ensuring system stability during power transitions. The MSOP package offers a compact form factor suitable for space-constrained designs. It complements other Analog Devices PMIC offerings by providing precise monitoring rather than regulation.
