DS1780E+T&R

Thermal Management Overview

The DS1780E+T&R is a CPU peripheral monitor and board-mount temperature sensor IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a power supply range of 2.8V to 5.75V and features an 8-bit resolution for analog-to-digital conversion. The device monitors ambient temperature, six power supply voltages, and two fan speeds. It utilizes a 2-wire serial interface with 2-bit addressability and includes an integrated NAND tree for board-level testability.

Thermal Management Feature Summary

• Monitors system parameters including temperature, multiple voltage rails, and fan speeds
• Provides remote system reset functionality with internal debounce and delay
• Includes chassis intrusion detection input for enhanced security
• Features an 8-bit DAC for direct fan speed control

Thermal Management Applications

• Monitoring in personal computers
• Microprocessor-based systems
• System instrumentation monitoring

Thermal Management Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation as required for your assembly process. Ensure the 24-pin TSSOP footprint matches your PCB layout constraints before finalizing procurement.

Thermal Management Selection Notes

Select this component for applications requiring high integration of thermal and electrical monitoring on a single chip. The wide supply voltage range supports both 3V and 5V system architectures. Consider the 2-wire interface compatibility with your host controller's available communication lines.

Thermal Management Part Context

This part belongs to the DS1780 series of CPU peripheral monitors from Maxim Integrated, now part of Analog Devices. It is designed to replace discrete monitoring solutions by consolidating temperature, voltage, and fan sensing into one compact package.

Thermal Management Replacement Considerations

Check for pin-compatible alternatives within the same family if availability is limited. Verify that any substitute maintains the 2-wire interface protocol and interrupt logic levels.
