It measures both its own die temperature (local) and an external diode-connected transistor (remote) over a 12-bit SMBus interface, with a best accuracy of ±1°C locally and ±2°C remotely across the full automotive temperature range. ## Supply, interface, and package constraints The SMBus output supports standard SMBus protocols including alert response and timeout — useful for multi-sensor bus architectures where a single master polls several TMP451 devices. Packaged in an 8-WSON (2x2.5 mm) with wettable flanks, the footprint allows automated optical inspection (AOI) of the solder joints after reflow — a requirement for automotive assembly lines that cannot rely on X-ray for every board. The small package suits space-constrained ECU designs. ## Active lifecycle and sourcing posture Texas Instruments lists the TMP451JQDQWRQ1 as Active (current production) and RoHS3 compliant.","metaTitle":"TMP451JQDQWRQ1 Texas Instruments Temp Sensor, ±1°C, SMBus","metaDescription":"TMP451JQDQWRQ1 digital local/remote temperature sensor from TI, AEC-Q100, ±1°C accuracy, SMBus output, 1.7-3.6V supply, 8-WSON package.
