The isoSPI isolated daisy-chain interface connects multiple devices in a stack without optocouplers. Internal balancing FETs allow passive cell equalization. AEC-Q100 qualified for automotive use.","working_principle":"A 16-bit delta-sigma ADC multiplexed across 15 cell inputs measures each cell voltage sequentially. The isoSPI interface encodes SPI data onto a differential pair with embedded isolation, allowing high-voltage daisy-chain connection between stack monitors on different potential levels. Internal MOSFETs across each cell provide passive balancing by shunting current around higher-voltage cells.","pin_description":"
