Infineon TLI4971A075T5UE0001XUMA1

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. Infineon's 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. Typical applications are electrical drives and general purpose inverters. The differential measurement principle allows great stray field suppression for operation in harsh environments. Two separate interface pins (OCD) provide a fast output signal in case a current exceeds a pre-set threshold. The sensor is shipped as a fully calibrated product without requiring any customer end-of-line calibration. All user-programmable parameters such as OCD thresholds, blanking times and output configuration modes are stored in an embedded EEPROM memory.
