产品概述
描述
L99BM2T/L99BM2TS are bidirectional SPI transceivers that, in a BMS system, allow communication between isolated devices in different voltage domains through a twisted-pair connection.
The devices belong to the L99BM2 chipset family for high-voltage battery management systems monitoring and control.
