INFINEON TLE4973RE35D5S0010XUMA1 Current Sensor, Hall Effect, Unidirectional, Bidirectional, ± 0.8%, TDSO, 16 Pins

TLE4973RE35D5S0010XUMA1 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). The potential application includes main and auxiliary electrical drives, over-load and over-current detection, battery main switch, smart circuit breakers, PV inverters, current monitoring, and power supplies.
