SNIS214 – JUNE 2021
www.ti.com 7 Detailed Description 7.1 Overview
The TMP114 is a digital output temperature sensor that comes factory calibrated on a NIST traceable setup. The device features a two-wire SMBus and I2C interface-compatible interface with two modes of operation: continuous mode and shutdown mode designed for thermal management and thermal protection applications. The TMP114 also includes an alert status register with individual high and low thresholds along with adjustable hysteresis values. Communication with the TMP114 has an integrated optional Cyclic Redundancy Check (CRC) module that will validate the data integrity of write and read operations.
