Infineon Technologies TLI4971 XENSIV™ current sensor

XENSIV™ – TLI4971 high-precision coreless current sensors

Infineon expanded their highly precise current sensor family by six more pre-programmed derivatives for even more applications such as industrial drives-electric drives up to 30 kW, PV inverters, and charging. The highest flexibility is offered by individually programmable parameters such as current range, overcurrent threshold, or output mode. Their sensors offer an accurate and stable current measurement, provided as an analog output voltage. Based on market-proven temperature and stress compensation technology, the sensitivity error is as low as 2% at room temperature. It can be reduced even below with a single point in-system calibration.

Key features

Three measurement ranges up to 25 A peak, 50 A peak, 75 A peak at 690 VRMS
Full scale measurement range ±25 A, ±50 A, and ±75 A
AC and DC measurement possible
Typical error at 25 °C: less than 2%

Additional features

Resistance of the current-rail 225 µΩ (typ.)
Analog output signal with 120 kHz bandwidth
Two separate outputs for overcurrent detection (OCD) feature
Programmable overcurrent detection threshold up to 2 times of the measurement range
Fast response time for overcurrent detection (< 1µs typ.)
Small TISON-8 package: 8 x 8 x 1 mm
Version with UL certification available

Additional Benefits:

Ultra-low-power loss due to the low resistance of current rail reduces cooling efforts
Reliable current measurement over the lifetime (no re-calibration)
Functional isolation for high voltage applications
Integrated overcurrent detection safes external circuitry
Two overcurrent pins with two independent overcurrent thresholds to define pre-warning and shut-off current
Programmable sensor to cover multiple frame sizes for drives
