MAX6604AATA+T

Thermal Management Overview

The MAX6604AATA+T is a high-precision temperature sensor designed for thermal monitoring in DDR memory modules. It operates from +2.7V to +3.6V and features an SMBus/I²C-compatible interface with a serial clock frequency of 400 kHz. The device provides ±1°C accuracy within the active range and supports up to eight devices on one bus via three address inputs. It updates temperature data eight times per second, offering programmable overtemperature interrupts and shutdown modes.

Thermal Management Feature Summary

• High-precision temperature monitoring with ±1°C accuracy in the active range
• SMBus/I²C-compatible interface supporting up to eight devices on a single bus
• Programmable overtemperature interrupt thresholds with comparator or interrupt modes
• Low-power operation with typical shutdown current of 3µA

Thermal Management Applications

• DDR Memory Modules
• Desktop Computers
• Notebook Computers
• Workstations
• Networking Equipment

Thermal Management Procurement Notes

Verify the specific suffix 'AATA' corresponds to the 8-pin TDFN-EP package when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Ensure compatibility with the host controller's I²C/SMBus voltage levels and pull-up requirements. Check for any obsolescence notices or lifecycle changes directly from Analog Devices/Maxim Integrated before finalizing procurement plans.

Thermal Management Selection Notes

Select this component when precise on-module thermal monitoring is required for DDR memory systems. It is suitable for applications needing fast response times compared to motherboard sensors. Consider the 8-pin TDFN package for space-constrained designs. Verify that the operating voltage range of 2.7V to 3.6V matches the system power rails. Ensure the host system supports the required SMBus/I²C protocol for register access.

Thermal Management Part Context

The MAX6604 series includes variants like the MAX6604AAHA+ in an 8-pin TSSOP package. Both share identical electrical characteristics and functionality but differ in physical footprint. The MAX6604AATA+T specifically utilizes the TDFN-EP package, which includes an exposed pad for improved thermal dissipation and grounding. This family is part of Maxim Integrated's portfolio of precision temperature monitors.

Thermal Management Replacement Considerations

The MAX6604AAHA+ is a direct pin-compatible alternative in an 8-pin TSSOP package. Verify package dimensions and thermal performance differences if replacing the TDFN variant with the TSSOP version. No other functional substitutes are documented in the provided datasheet.
