TLI4971-A120T5-E0001 120 A, 3.45 %, 3.1-3.5V
XENSIV™ - TLI4971-A1205T5-E001 magnetic current sensor for AC and DC measurements in industrial applications
The Infineon XENSIVTM TLI4971 is a new high precision miniature coreless magnetic current sensor for AC and DC measurements with analog interface and dual fast over-current detection outputs.
Infineon's 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
