ADM1184ARMZ

Supervisors Overview

The ADM1184ARMZ is a quad-channel voltage monitor and sequencer manufactured by Analog Devices Inc. It features adjustable or selectable overvoltage thresholds with 0.8% accuracy. The device provides active high, open-drain reset outputs and operates within a supply voltage range of up to 5.5 V. It includes a fixed reset delay time of 190 ms and consumes 24 uA of operating current. The component functions without manual reset or watchdog timer capabilities and supports surface mount installation in a 10-MSOP package across an industrial temperature range.

Supervisors Feature Summary

• Integrates four independent voltage monitoring channels with adjustable threshold settings for precise power supervision.
• Generates active high reset signals via open-drain outputs to indicate valid power conditions.
• Includes internal sequencing logic to manage power-up and power-down transitions automatically.
• Operates with low quiescent current consumption suitable for battery-powered applications.

Supervisors Applications

• Multi-rail power system supervision in embedded controllers
• Voltage monitoring for FPGA and microprocessor power domains
• Industrial equipment requiring sequential power ramping
• Telecommunications infrastructure power management

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when ordering. Confirm the 10-MSOP package dimension matches your PCB footprint requirements. Ensure the 5.5 V maximum supply rating aligns with your system voltage rails. Check that the open-drain output configuration fits your pull-up resistor design. Validate the -40°C to +85°C operating temperature range meets your environmental specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring with sequenced reset generation. The adjustable thresholds allow customization for various standard voltage levels without external resistors. The open-drain output simplifies interfacing with different logic families. Consider the 190 ms reset delay for timing-sensitive applications. Evaluate the 24 uA current draw against total system power budgets.

Supervisors Part Context

This part belongs to the ADM1184 series of voltage monitors from Analog Devices. It complements other PMIC supervisory devices by offering multi-channel capability in a compact MSOP package. The series focuses on providing reliable power sequence control for complex digital systems. It serves as a dedicated solution for managing multiple power domains without requiring discrete comparator circuits.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct pin-compatible alternatives within the ADM118x family. Verify if ADM1186 offers similar functionality with potential interface differences. Confirm electrical parameters match before substitution. Review datasheet revisions for any functional updates in newer variants.
