HVBMS Battery Junction Box Using ETPL with MC33772C (BJB)

RD772BJBTPLEVB

Roll over image to zoom in

The RD772BJBTPLEVB is a battery junction box (BJB) 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 two MC33772C battery sensors for redundant high voltage and current measurements and performs isolation measurements.

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