MC33742SPEG

MC33742SPEG is a system basis chip with enhanced high speed CAN transceiver. It is SPI-controlled system basis chips (SBCs), combining many frequently used functions, along with a CAN 2.0-compliant transceiver, used in many automotive electronic control units (ECUs). This SBC has a fully protected fixed 5V low dropout internal regulator, with current limiting, overtemperature prewarning, and reset. A second 5V 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.
