Infineon Technologies AGTLI4971A120T5E0001XUMA1Current Sensors
High precision coreless current sensor with an analog interface and dual fast over-current detection outputs
Our XENSIV™ - TLI4971 is a new Infineon high precision 8x8x1mm leadless QFN package coreless magnetic current sensor for AC and DC measurements with an analog interface and dual fast over-current detection outputs.
The Infineon well-established and robust Hall technology enables accurate and highly linear measurement of currents with a full measurement range up to ±120A. All negative effects (saturation, hysteresis) commonly known from sensors using flux concentration techniques are avoided. The current sensor is equipped with internal self-diagnostic feature.
The digitally assisted analog concept of TLI4971 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.
We offer two derivatives:
TLI4971-A120T5-U-E0001 with 120A measurement range, UL certified device
TLI4971-A120T5-E0001 120A measurement range
