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 well-established Infineon TLI4970 combines superior accuracy with one output pin for overcurrent detection signal. The measurement signal is provided through a 3-pin serial peripheral interface (SPI) using a standard unidirectional 16-bit SPI protocol is used. Several sensors can be connected to a parallel SPI bus.
Infineon XENSIV™ TLI4971 current sensor dedicated for industrial applications
Infineon Technologies AG will launch a new family of current sensors and presented its first member at this year’s PCIM trade fair. The family will consist of precise and stable coreless Hall sensors. They offer a high level of flexibility as customers can individually program product parameters such as the current range, the overcurrent threshold and the output mode. This new sensor will be coming soon.
