800 V Battery Junction Box Using ETPL with MC33772C

RD772BJBTPL8EVB

Roll over image to zoom in

The RD772BJBTPL8EVB is a battery junction box (BJB) 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 two MC33772C battery sensors for redundant high voltage and current measurements and performs isolation measurements.

This board is part of the RD-HVBMSCT800BUN reference design bundle using ETPL.
