HVBMS Centralized Cell Monitoring Unit Using ETPL with MC33774ATP

RD33774PC3EVB

Roll over image to zoom in

The RD33774PC3EVB is a centralized cell monitoring unit (CMU) reference design with electrical transport protocol link (ETPL) communication. It is ideal for rapid prototyping of a 800 V high-voltage battery management system (HVBMS) hardware and software. This board contains three MC33774 analog front ends (AFEs) in a daisy chain.
