Current sensors for measurement up to 120A

Overview

XENSIV? - high-precision coreless current sensors for industrial applications

The Infineon current sensors provide accurate and stable current measurement up to 120A. The products are intended for use in high-voltage industrial applications such as electric drives, photovoltaic inverters, power supplies or battery management systems.

The coreless open-loop sensors are based on Infineon’s precise and stable Hall technology. Thus the output signal is highly linear over temperature and lifetime. Due to lack of an iron core the sensor signal shows neither hysteresis nor does it suffer from saturation. Due to the integrated current rail there is no need for external calibration. The differential measurement with two Hall cells ensures high accuracy even in a noisy environment with cross-talk from adjacent current lines or magnetic stray fields. 

Highlights of the XENSIVTM TLI4971 include best-in-class thermal performance for high currents due to its innovative TISON-8 package as well as isolation against high voltages. The two output pins for fast overcurrent signals can be used for pre-warning and system shut-down. Designers can program the threshold levels of the overcurrent signals and thus adapt them to individual requirements without any external components. The sensor also provides a signal in case of an over- or under-voltage condition for the supply voltage.

The REF_22k_GPD-INV_Easy3B GPD Reference Design Kit provides industry’s best performance by using Infineon’s newest technologies. The power module is the new Easy3B FP100R12W3T7_B11 populated with the newest TRENCHSTOP? IGBT7 technology in PIM configuration. For enhanced control of the IGBT7, the galvanically isolated single-channel gate driver 1ED3131MC12H with low inductive losses is used enabling an additional gain in efficiency of up to 0.5 percent. For controlling and sensing the current, the coreless current sensor TLI4971 features a unique combination of current measurement for motor control and short-circuit protection of the IGBT. The power supply of the inverter is implemented with a flyback inverter equipped with a 1.7 kV CoolSiC? MOSFET IMBF170R1K0M1.
