SYSTEM BASIS CHIP

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.
