AD5100YRQZ

Overview

The AD5100YRQZ is a system management integrated circuit manufactured by Analog Devices Inc., designed for programmable quad voltage monitoring and supervisory functions. It features four independent channels with adjustable or selectable voltage thresholds, allowing precise configuration for specific application requirements. The device utilizes a push-pull or totem pole output structure and provides a low-active reset signal with a standard timeout of 60 microseconds. It operates within a temperature range of -40°C to 125°C and is housed in a 16-lead QSOP surface-mount package.

Feature Summary

• Programmable quad voltage monitoring with adjustable or selectable thresholds
• Low-active reset output with standard 60µs timeout
• Push-pull/totem pole output structure for robust signaling

Applications

• System management in industrial equipment
• Voltage supervision in embedded systems
• Power supply monitoring in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance and EAR99 classification for export purposes. Check current availability status as the part may be discontinued or subject to supply limitations. Ensure packaging specifications match project requirements, noting the 16-QSOP form factor.

Selection Notes

Select this component when multi-channel voltage supervision with configurable thresholds is required. Consider the 16-QSOP package for space-constrained designs. Evaluate the -40°C to 125°C operating range against environmental conditions. Verify that the low-active reset polarity and 60µs timeout align with system timing constraints.

Part Context

The AD5100 series belongs to Analog Devices' system management portfolio, focusing on power supply monitoring and supervisory circuits. This specific variant integrates four monitoring channels into a single compact package, simplifying board layout compared to discrete solutions. It serves as a critical component for ensuring system reliability by detecting abnormal voltage conditions across multiple rails.

FAQ

What is the reset output polarity of the AD5100YRQZ?

The reset output is low-active, meaning it asserts a logic low signal when a fault condition is detected.

Can the voltage thresholds be adjusted after manufacturing?

Yes, the AD5100YRQZ features adjustable or selectable voltage thresholds, allowing configuration to meet specific application needs.
