MAX20480DI/VY+CTJ

Supervisors Overview

The MAX20480DI/VY+CTJ is a multi-channel voltage supervisor IC from Analog Devices. It features seven independent monitoring channels with open-drain or open-collector outputs. The device operates within an input voltage range of 3V to 36V and supports output currents up to 6A in associated buck converter configurations within its family. It functions as a power supply monitor with a shutdown capability. The component is housed in a 16-pin SW-TQFN package (3x3 mm) with exposed pad for thermal management. It is designed for industrial applications requiring robust voltage supervision across multiple rails.

Supervisors Feature Summary

• Provides seven independent voltage monitoring channels for comprehensive system supervision
• Features open-drain or open-collector outputs for flexible interfacing with various logic levels
• Includes shutdown functionality to minimize power consumption during inactive states
• Operates reliably across a wide temperature range suitable for industrial environments

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision for embedded computing platforms
• System reset generation in communication equipment
• Battery management system oversight

Supervisors Procurement Notes

Verify the exact suffix CTJ against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices as distribution availability may vary. Ensure the supplier provides genuine components with traceable date codes. Validate pinout compatibility with existing PCB layouts before procurement.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a compact footprint. Consider the 16-pin TQFN package for space-constrained designs. Evaluate the need for seven channels versus simpler single-channel supervisors. Assess thermal requirements given the exposed pad design. Verify input voltage ranges match the specific application rails being monitored.

Supervisors Part Context

This part belongs to the MAX204xx series of power management ICs from Maxim Integrated, now part of Analog Devices. The series includes buck converters and supervisors designed for high-efficiency power solutions. The MAX20480 specifically focuses on voltage supervision rather than conversion, complementing other parts like the MAX20406 which handles buck conversion. This integration allows for complete power management solutions in single packages.

Supervisors Replacement Considerations

Check Analog Devices official substitution lists for direct replacements. Verify pin-to-pin compatibility if considering alternative suppliers. Ensure electrical parameters such as threshold voltages and output drive capabilities match original requirements. Review package dimensions for mechanical fit in existing assemblies.
