Thermal Management Procurement Notes

Verify the specific suffix 'F' against the official Texas Instruments datasheet to confirm exact pinout and functional configuration. Ensure compatibility with the required 3 V to 3.6 V supply voltage and selected communication protocol (I2C/SMBus/2-wire). Confirm that the WQFN-24 package dimensions meet the PCB layout requirements. Check for any specific ordering or marking variations documented in the manufacturer's latest release notes.

Thermal Management Selection Notes

Select this component when simultaneous local and remote temperature monitoring is required alongside active cooling control. The 10-bit resolution and +/- 1 °C accuracy suit applications demanding moderate precision without complex calibration. Verify that the system design accommodates the specified 3 V to 3.6 V power supply constraints. Ensure the chosen communication interface aligns with the host controller's available digital buses.
