Description
TLI4971 is a high precision miniature coreless magnetic current sensor for AC and DC measurements with analog interface and two fast over-current detection outputs.
Infineons well-established and robust monolithic Hall technology enables accurate and highly linear measurement of currents with a full scale up to ±120A. All negative effects (saturation, hysteresis) commonly known from open loop sensors using flux concentration techniques are avoided. The sensor is equipped with internal self-diagnostic feature.
