The Infineon current sensor TLE4971-A120T5-U-E0001 is an automotive qualified pre-programmed 120 A sensor. It serves the unique ±120 A measurement rage, the highest for current sensors with integrated current rail in a small SMD body and introduces a new package developed to enable optical inspection in the assembly line. Due to the coreless magnetic current sensing principle, saturation or hysteresis effects commonly known from sensors using flux concentration techniques are avoided. The analog interface and two dedicated fast over-current detection pins with a reaction time of less than 1 µs ensures a safe operation of systems.Infineon's well-established and robust Hall technology enables accurate and highly linear measurement of, rated as high currents, AC and DC currents with a full measurement range up to ±120 A full scale range. All negative effects (saturation, hysteresis) commonly known from sensors using flux concentration techniques are avoided.The digitally assisted analog concept of TLE4971 offers superior stability over temperature and lifetime thanks to the proprietary digital stress and temperature compensation. The differential measurement principle allows great stray field suppression for operation in harsh environments up to 125°C.We offer two derivatives: TLE4971-A120T5-U-E0001 with 120A measurement range, UL certified device TLE4971-A120T5-E0001 with 120 A measurement range
