Magnetic Current Sensor
High-precision current sensor
TLI4970 is a high-precision current sensor for industrial applications based on our proven Hall technology. The core-less concept significantly reduces footprint compared with existing solutions. Infineon´s TLI4970 is an easy-to-use, fully digital solution that does not require external calibration or additional parts such as A/D converters, 0 pAmps or reference voltage. It thus significantly reduces overall implementation effort as well as PCB space and cost.
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.
Furthermore Infineon´s current sensor is more accurate than existing open-loop and com-parable to closed-loop systems.
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.
