Interfacing Current Output Hall Sensors and CTs with Pseudo-differential ADC/MCU Reference Design
Description
This reference design provides interfacing current output Hall sensors and current transformers to pseudo-differential ADC (standalone and integrated into MCU). Two variants of signal conditioning circuits are designed to measure motor current using bipolar and unipolar supply voltages respectively. Both of the signal conditioning circuits provide current measurement accuracy within ±0.5% for an operating temperature range from -25 °C to 75 °C.
Features
- On-board current-output Hall sensor to measure nominal current up to 25-A RMSCurrent measurement accuracy of 0.5%Common reference for interfacing both CT and current output Hall sensor with pseudo-differential ADC/MCUTwo different variants to work on unipolar and bipolar supply railsDesigned to evaluate with Delfino F2837x control cardDesigned to evaluate with external ADC (ADS7253) for interfacing with motor controller
