TLE4971-A025N5-E0001 | 25 A, <2 %, 3.1-3.5V

Overview

XENSIV™ - TLE4971-A025N5-E0001 high precision coreless current sensor with analog interface and dual fast over-current detection outputs

The Infineon XENSIV TLE4971-A025N5-E0001 is our brand new automotive current sensor, pre-programmed to the 25A measurement range. It 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 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.

We offer two derivatives:

TLE4971-A025N5-U-E0001 with 25A measurement range, UL certified device
TLE4971-A025N5-E0001 with 25A measurement range
