New Product Introduction

Infineon Technologies XENSIV™ - TLE4973

Automotive current sensors in TISON package

Infineon Technologies XENSIV™ - TLE4973 product image

TLE4973 works at 5 V with an analog output as well as over current detection output. One digital control and diagnostic interface provides temperature readout, safety status readout, read/write programming access to internal EEPROM. Infineon's Hall technology enables accurate and highly linear measurement. TISON-8-6 package enables optical inspection in the assembly line. The measurement range of up to ± 132 A allows to sense currents without negative effects, e.g. hysteresis and saturation.
