The differential measurement principle integrated in the TLI4970 sensor suppresses interference caused by external magnetic fields. Accordingly, the sensor achieves an ex-tremely low offset of just 25 mA.
With conventional current measurement principles, the measuring accuracy is always governed by the ambient conditions (e.g. the temperature).
Furthermore Infineon´s current sensor is more accurate than existing open-loop and com-parable to closed-loop systems.
It also provides additional functions such as fast overcurrent detection and program-mable filters yet has a significantly smaller footprint and lower power consumption.
The sensor is extremely robust against external magnetic fields thanks to implemented stray field suppression and is also suitable for fast overcurrent detection at a pre-con-figurable level. This allows the control unit to switch off independently of the main measurement path and protect power consumers from damage.
