This reference design demonstrates an accurate low latency reinforced isolated bidirectional current sense system using the TMCS1123 precision Hall-effect current sensor for reliable phase current and DC-link current sensing with three phase inverters up to ±62A and less than 100ns over-current detection time. The overcurrent threshold is configurable up to 2.5-times the full-scale input current range. A small formfactor 12-bit A/D converter with high-speed SPI or a delta-sigma modulator with up to 21 MHz clock offer a high noise immunity 3.3V I/O digital interface. The interface connects to host processors like a C2000 or Sitara MCU for easy performance evaluation of in-package hall-sensors with different A/D conversion technologies.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
