TLI4970-D050T4 CurrentSense Shield2Go Quick Start V1.0.0 Introduction The TLI4970-D050T4 is a highly accurate coreless magnetic current sensor. Thus, the output signal is highly linear and without hysteresis. However, a differential measurement principle allows effective stray field suppression. Due to the integrated primary conductor (current rail), there is no need for external calibration. Additionally, a separate interface pin (OCD) provides a fast output signal in case a current exceeds a pre-set threshold. A small leadless package (QFN-like) allows for standard SMD assembly. Key features are a AC & DC measurement range up to 50 A, highly accurate over temperature range and lifetime of max. 1.0 % (0 h), 1.6 % (over lifetime) of indicated value, low offset error (max. 25 mA at room temperature) and a high magnetic stray field suppression. Additionally, the sensor has fast over current detection with configurable threshold and a galvanic isolation up to 2.5 kV max. rated isolation voltage. The sensor has a 16 bit digital SPI output (13 bit current value). Link to Datasheet and Product Page 2018-07-17 Copyright Infineon Technologies AG 2018. All rights reserved. 2
