MC33742PEG

MC33742PEG is a system basis chip with enhanced high speed CAN transceiver. SMARTMOS device is SPI-controlled System Basis Chip (SBC), combining many frequently used functions, along with a CAN 2.0-compliant transceiver, used in many automotive electronic control units (ECUs). The 33742 SBC has a fully protected fixed 5.0V low dropout internal regulator, with current limiting, overtemperature prewarning, and reset. A second 5.0V regulator can be implemented using external pass PNP bipolar junction pass transistor, driven by the SBC’s external V2 sense input and V2 output drive pins. The SBC has four main operating modes: Normal, Standby, Stop, and Sleep mode. Additionally, there is an internally switched high side power supply output, four wake-up inputs pins, a programmable window watchdog, interrupt, reset, and a SPI module for communication and control. The high speed CAN A and B transceiver is available for intermodular communication.
