TLE4973A120T5S0001XUMA1

TLE4973A120T5S0001XUMA1 is a high-precision miniature coreless magnetic current sensor for AC and DC measurements with an analogue interface and fast over-current detection output. Negative effects (saturation, hysteresis) known from open loop sensors using flux concentration techniques are avoided. The differential measurement principle allows great stray field suppression for operation in harsh environments. The high configurability enables customization for a variety of applications. User-programmable parameters such as OCD thresholds and sensitivity settings are stored in an embedded EEPROM. Device configuration can be performed in-situ through a one-wire UART-based interface called digital control diagnostic interface (DCDI). It is used in applications such as general-purpose electrical drives, chargers and on-board chargers, PV inverters, smart circuit breakers and uninterruptible power supply (UPS), over-load and over-current detection, current monitoring and power supplies.
