The TMP401 from Texas Instruments is a versatile digital temperature sensor designed for monitoring both remote and local temperatures. It features a high accuracy of ±1°C for the remote diode sensor and ±3°C for the built-in local temperature sensor. The device supports a wide remote temperature measurement range up to +150°C and operates within an ambient temperature range of -40°C to 125°C.
With its SMBus-compatible two-wire serial interface, the TMP401 allows for easy programming of alarm thresholds and reading of temperature data. Key features include series resistance cancellation, diode fault detection, and programmable resolution from 9 to 12 bits. The sensor is available in a VSSOP-8 package, suitable for surface mount applications.
This temperature sensor is ideal for applications requiring precise temperature monitoring, such as in servers, workstations, desktop and notebook computers, and telecom infrastructure. Its ability to monitor external PN junctions, like those found in microcontrollers or FPGAs, makes it a flexible solution for various thermal management needs.
