Hot-selling and scarce MC33742PEGR2 System Basis Chip with Enhanced High Speed CAN Transceiver SOP28 spot stock

Product Descriptions

The 33742 and the 33742S SMARTMOS devices are 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). The 33742 SBC has a fully protected  fixed 5.0 V low dropout internal regulator, with current limiting,  overtemperature prewarning, and reset. A second 5.0 V 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  intermodule communication.
