NXP Semiconductors RD33775ACNCEVB Evaluation Board

NXP Semiconductors RD33775ACNCEVB Evaluation Board implements a hardware reference design for centralized cell monitoring unit to communicate directly via CAN or CAN FD. The RD33775ACNCEVB features an MC33665A gateway router that can deliver TPL messages from CAN or CAN FD to four different TPL ports.

The NXP MC33775A ASIL D safety battery cell controller monitors the lithium-ion cell voltages and temperature while balancing the lithium-ion cells. The RD33775ACNCEVB Board can monitor up to 56 lithium-ion cells via four MC33775A battery cell controllers.
