UJA1131A Buck/boost HS-CAN/(dual) LIN system basis chip

UJA1131A Buck/boost HS-CAN/(dual) LIN system basis chip

The UJA113xA System Basis Chip (SBC) contains a fully integrated buck and boost converter along with a number of features commonly found in the latest generation of automotive Electronic Control Units (ECUs). It interfaces directly with CAN and LIN bus lines, supplies the microcontroller, handles in.
