MAX16048ETN+

Supervisors Overview

The MAX16048ETN+ is an EEPROM-programmable system manager featuring eight voltage monitoring channels. It operates within a supply voltage range of 2.7V to 5.25V and monitors up to eight distinct power rails. The device utilizes a 56-TQFN (8x8) package with a 0.5mm terminal pitch. It includes nonvolatile fault registers for event logging and supports open-drain or push-pull outputs. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• EEPROM programmability allows customization of reset thresholds and timing parameters without external components.
• Integrated nonvolatile fault registers capture and retain system failure events for diagnostic analysis.
• Configurable output drivers support both open-drain and push-pull configurations for flexible interface compatibility.

Supervisors Applications

• Multi-rail server and storage system power management
• Industrial control board voltage supervision
• Telecommunications infrastructure equipment monitoring

Supervisors Procurement Notes

Verify the specific suffix 'ETN+' ensures the lead-free RoHS-compliant variant. Confirm the 56-TQFN package dimensions match the target PCB footprint. Ensure the design accounts for the 2.7V minimum operating voltage. Validate that the required number of monitored channels aligns with the eight-channel capacity of this specific part number.

Supervisors Selection Notes

Select this component when multiple independent voltage rails require simultaneous supervision with customizable reset behaviors. The EEPROM programming capability eliminates the need for fixed-threshold comparators, reducing bill-of-materials complexity. Consider the 56-pin form factor for space-constrained designs requiring high channel density without sacrificing monitoring accuracy.

Supervisors Part Context

This device belongs to Maxim Integrated's family of EEPROM-programmable system managers. These components are designed to replace discrete supervisor circuits in complex electronic systems. The series provides integrated fault logging and programmable logic, streamlining power-up and power-down sequences in multi-voltage applications.

Supervisors Replacement Considerations

Check for direct pin-compatible upgrades within the MAX16048 series offering additional channels or different package options. Verify functional equivalence if substituting with older revisions, ensuring EEPROM programming commands remain compatible. Confirm thermal performance matches the original design requirements under identical load conditions.
