ADM1186-2ARQZ

Supervisors Overview

The ADM1186-2ARQZ is a quad voltage sequencer and monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features four independent channels for power monitoring. The device utilizes an SSOP-16 package (RQ-16) with 16 pins. It includes programmable timing capabilities for sequencing power rails and monitors voltages against user-defined under-voltage thresholds. If any monitored supply drops below the threshold, the internal state machine triggers a fault condition.

Supervisors Feature Summary

• Provides sequential control of four power supplies via an integrated state machine
• Monitors multiple voltage rails to ensure they remain above defined under-voltage thresholds
• Automatically shuts down all outputs upon detection of a fault condition

Supervisors Applications

• Sequential power-up and power-down management in embedded systems
• Multi-rail power supply monitoring in industrial equipment
• Fault protection circuits requiring coordinated shutdown of multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix '2' in the part number ADM1186-2ARQZ against official Analog Devices documentation to confirm functional variations or pinout differences compared to other variants in the ADM1186 family. Ensure the SSOP-16 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through current manufacturer declarations.

Supervisors Selection Notes

Select this component when designing systems requiring synchronized sequencing of four distinct power rails. It is suitable for applications where maintaining strict voltage hierarchy during startup is critical. Consider the SSOP-16 package constraints and the need for external components if additional timing adjustments are required beyond the internal programmable settings.

Supervisors Part Context

This component belongs to the ADM1186 series of power supply support circuits from Analog Devices. These devices are designed to manage complex power sequences in microprocessor and FPGA systems. The ADM1186-2 variant specifically addresses the needs of designs requiring four-channel monitoring with integrated fault handling logic.

Supervisors Replacement Considerations

Check for ADM1186-1ARQZ or ADM1186-3ARQZ as potential family members. Verify if alternative pin-compatible sequencers from other manufacturers meet the specific timing and voltage threshold requirements.
