TLE4971-A025T5-E0001 25 A, <2 %, 3.1-3.5V, optical inspection
XENSIV™ - TLE4971-A025T5-E0001 high precision coreless current sensor with analog interface and optical inspection capable small SMD package
The Infineon TLE4971-A025T5-E0001 is the latest member of our automotive current sensor family with a new package developed to enable optical inspection in the assembly line. It’s pre-programmed to the 25A measurement range and offers high precision current measurement in applications with lower currents. This improved design of a coreless magnetic current sensor solution is usable for AC and DC measurements. It consists of an analog interface and two fast over-current detection outputs.
Infineon's well-established and robust Hall technology enables accurate and highly linear measurement of rated as low currents with a full measurement range up to ±25A 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.
