产品概要
描述
L9965TE and L9965TSE are bidirectional SPI transceivers that, in a BMS system, allow communication between isolated devices into different voltage domains through a twisted-pair connection. The devices belong to the L9965 chipset family for high-voltage battery management systems monitoring and control.
