Overview
The TMP512AIRSAR is a board-mount temperature sensor IC from Texas Instruments, housed in a QFN-16 package. It features a digital output with 12-bit resolution and an accuracy of +/- 1 C. The device operates on a supply voltage ranging from 3 V to 26 V and supports 2-Wire, I2C, and SMBus interfaces. It monitors both local and remote temperatures within a working range of -40 C to +125 C. The component includes a shutdown configuration and draws 1.4 mA during operation.
Feature Summary
- Integrates local and remote temperature sensing capabilities within a single system monitor solution.
- Provides high-resolution digital conversion via a 12-bit analog-to-digital converter interface.
- Supports multiple standard communication protocols including I2C and SMBus for flexible system integration.
Applications
- Thermal monitoring in industrial control systems
- Temperature sensing in embedded computing hardware
- Power management supervision in server infrastructure
Procurement Notes
Verify the specific suffix 'AR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing I2C or SMBbus address configurations in the target design. Check for any recent product change notices regarding moisture sensitivity levels or material composition updates before finalizing procurement orders.
Selection Notes
Select this component when precise local and remote thermal monitoring is required within a compact surface-mount footprint. The wide supply voltage range accommodates various system power rails without additional level shifting. Consider the 12-bit resolution and +/- 1 C accuracy for applications demanding detailed thermal data acquisition over standard 8-bit sensors.
Part Context
This part belongs to the TMP512 series of all-in-one thermal and power monitor solutions by Texas Instruments. It is designed as a direct replacement for legacy monitoring functions, consolidating temperature sensing and system health checks into a single integrated circuit. The series targets applications requiring reliable thermal management in space-constrained electronic assemblies.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives if the TMP512AIRSAR is unavailable. Verify that any substitute maintains the same QFN-16 package dimensions and electrical interface compatibility to ensure seamless integration without PCB redesign.
