TLE4971-A050T5-E0001 50 A, <2 %, 3.1-3.5V, optical inspection
XENSIV™ - TLE4971-A050T5-E0001 high precision coreless current sensor with analog interface and optical inspection capable small SMD package
The Infineon TLE4971-A050T5-E0001 is the latest member of our automotive qualified (AEC-Q100) current sensor family, pre-programmed to the 50A measurement range and a new package developed to enable optical inspection in the assembly line. In applications with medium currents, this coreless magnetic current sensor solution is usable for AC and DC measurements. Due to its 240kHz bandwidth the fast analog interface and two fast over-current detection outputs as well as the high precision current measurement ensures high flexibility in many application use cases.
Infineon's well-established and robust Hall technology enables accurate and highly linear measurement of medium rated currents with a full measurement range up to ±50A 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.
