Pin Configuration

Figure 1 Pin layout PG-TISON-8

The current IPN is measured as a positive value

when it flows from pin 8 (+) to pin 7 (-) through the

integrated current rail.

Target Applications

The TLE4971 is suitable for AC as well as DC current measurement applications:

•

On-Board Charger (OBC)

•

Drives / Servo / Motor Control / Inverter / eScooter / eBike / LEV

•

Current monitoring

•

Overload and over-current detection

Due to its implemented magnetic interference suppression, it is extremely robust when exposed to external

magnetic fields. The device is suitable for fast over-current detection with a configurable threshold level.

This allows the control unit to switch off and protect the affected system from damage, independently from

the main measurement path.
