Overview
The TMP512AIRSAT is a board-mount temperature sensor IC from Texas Instruments, part of the TMP512 series. It functions as an all-in-one thermal and power monitor solution with digital output. The device features a QFN-16 package and supports I2C/SMBus interfaces. It operates within a supply voltage range of 3V to 26V and maintains an accuracy of +/- 1°C. The operational temperature range spans from -40°C to +125°C. It includes local and remote configuration options, a 12-bit resolution, and a shutdown feature.
Feature Summary
- Integrates local and remote temperature sensing capabilities for comprehensive thermal monitoring.
- Supports standard digital communication protocols including I2C and SMBus interfaces.
- Provides high accuracy performance suitable for precise system monitoring applications.
Applications
- System thermal management in industrial equipment
- Power supply monitoring in server infrastructure
- Temperature sensing in embedded computing systems
Procurement Notes
Verify the specific suffix 'SAT' against the manufacturer's current datasheet to confirm package type and availability status. Ensure compatibility with existing I2C/SMBus bus configurations. Check for moisture sensitivity level requirements during storage and handling. Confirm RoHS compliance documentation matches project specifications. Validate that the 16-QFN footprint aligns with the PCB design constraints.
Selection Notes
Select this component when both local and remote temperature monitoring are required within a single integrated circuit. The wide operating voltage range accommodates various system power rails. The digital interface simplifies integration with microcontrollers or processors supporting standard serial protocols. Consider the QFN-16 package size for space-constrained designs requiring surface mount technology.
Part Context
This component belongs to the TMP512 family of hardware monitors designed for board-level thermal management. It consolidates multiple sensing functions into a single small-footprint device. The series is intended for applications requiring reliable temperature data acquisition without external sensor components. It serves as a direct replacement for discrete temperature sensing solutions in modern electronic systems.
Replacement Considerations
TMP512AIRSAR is a verified substitute with identical electrical characteristics but potentially different packaging or reel configuration. Verify pinout compatibility before substitution. Ensure the alternative suffix meets the same accuracy and temperature range requirements.
