The Infineon XENSIV TLE4971-A120N5-E0001 is a new automotive qualified pre-programmed 120A sensor. It serves the unique ±120A measurement rage, the highest for current sensors with integrated current rail in a small SMD body. 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 1µs ensures a safe operation of systems. Infineon's well-established and robust Hall technology enables accurate and highly linear measurement of AC and DC currents with a full measurement range up to ±120A 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:
