Overview

The TLI4970-D050T5 is an 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.
