UJA113xA series Buck/boost HS-CAN/(dual) LIN system basis chip Rev. 1 — 28 March 2024 Product data sheet 1 General description 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 input and output signals and supports fail-safe features including a watchdog and advanced ‘limp home’ functionality configurable via non-volatile memory. The UJA113xA is available in number of variants as detailed in Section 3.
