Called TLE4971, they “ are, according to the company, ideal for on-board chargers, high voltage auxiliary drives and chargers". "Furthermore, the sensor is also ideal for industrial applications, including DC chargers for electric vehicles, industrial drives, servo drives and photovoltaic inverters."
Inside, the current sensor is magnetic, with temperature. and voltage compensation “without the negative impact of magnetic cores caused by hysteresis or saturation effects,” Infineon said. Differential metering is used to eliminate the need for a core or shield to protect against stray fields. The insertion resistance is 220 μΩ, and the introduced inductance is <1 nH.
A 3.1 to 3.5 V power supply is required and the output is analog - depending on the option programmed, the output can be single-ended, fully differential or semi-differential.
