HVBMS Centralized Cell Monitoring Unit Using ETPL with MC33775A (CMU)

RD33775ACNTEVB Active

Roll over image to zoom in

The RD33775ACNTEVB is a centralized cell monitoring unit (CMU) reference design with electrical transport protocol link (ETPL) communication. It is ideal for rapid prototyping of a high-voltage battery management system (HVBMS) hardware and software. This board contains four MC33775A analog front ends (AFEs) in a daisy chain.

This board is part of the RD-HVBMSCTBUN HVBMS reference design bundle using ETPL.
