Product Description
1.1
Overview
The TLI4970-D025T4 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.
