TLE4971-A075T5-U-E0001 | 75 A, <2 %, 3.1-3.5V, UL/CSA

Overview

XENSIV™ - TLE4971-A075T5-U-E0001 high precision coreless current sensor with analog interface and optical inspection capable small SMD package, UL certified device

The Infineon current sensor TLE4971-A075T5-U-E0001 is the latest edition to our automotive qualified product family, a pre-programmed 75A current sensor. A new package developed to enable quality control only via optical inspection in the assembly line is introduced with this product. The high precision current measurement serves applications with medium to high currents. 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 fast over-current detection pins with a reaction time of less than 1µs ensures a safe operation of the applications.

Infineon's well-established and robust Hall technology enables accurate and highly linear measurement of AC and DC currents, rated as medium to high currents, with a full measurement range up to ±75A 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.
