The RD33774CNT3EVB is a centralized cell monitoring unit (CMU) reference design with electrical transport protocol link (ETPL) communication. It is meant 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. This board is part of the RD-HVBMSCT800BUN reference design bundle using ETPL.
