方案关键器件表：

　　MC33742

　　The 33742 and the 33742S 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 wakeup 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 inter-module communication.

　　Features

　　•1.0 Mbps CAN Transceiver Bus Interface with Bus Diagnostic Capability

　　•SPI Control at Frequencies up to 4.0 Mhz

　　•5.0 V Low Dropout Voltage Regulator with Current Limiting,

　　Overtemperature PreWarning, and Output Monitoring and Reset

　　•A Second 5.0 V Regulator Capability using an External Series Pass Transistor

　　•Normal, Standby, Stop, and Sleep Modes of Operation with Low Sleep and Stop Mode Current

　　•A High-Side (HS) Switch Output Driver for Controlling External Circuitry.

　　•Pb-Free Packaging Designated by Suffix Code EG and EP

　　MC33902

　　The MC33902 is a high speed CAN physical interface. The device includes an internal 5.0 V supply for the CAN bus transceiver, and requires only a connection to a battery line.

　　The MC33902 provides 4 operation modes, including low power modes with remote and local wake-up.

　　The device has very low sleep and standby current consumption.

　　Features

　　•High speed CAN interface for baud rates of 40 kb/s to 1.0 Mb/s

　　•Compatible to ISO11898 standard

　　•Single supply from battery. No need for a 5.0 V supply for CAN interface

　　•I/O compatible from 2.75 V to 5.5 V via a dedicated input terminal (3.3 V or 5.0 V logic compatible)

　　•Low Power mode with remote CAN wake-up and local wake-up recognition and reporting

　　•CAN bus failure diagnostics and TXD/RXD pin monitoring, cold start detection, wakeup sources reported through the ERR pin•Enhanced diagnostics for bus, TXD, RXD and supply pins available through Pseudo SPI via existing terminals EN, STBY and ERR.

　　•Split terminal for bus recessive level stabilization•INH output to control external voltage regulator•Pb-free packaging designated by suffix code EF

　　MC33661

　　Local Interconnect Network (LIN) is a serial communication protocol

　　designed to support automotive networks in conjunction with Controller Area Network (CAN). As the lowest level of a hierarchical network, LIN enables cost-effective communication with sensors and actuators when all the features of CAN are not required.

　　The 33661 is a Physical Layer component dedicated to automotive LIN sub-bus applications. It offers slew rate selection for optimized operation at 10kbps and 20kbps, fast baud rate (above 100kbps) for test and

　　programming modes, excellent radiated emission performance, and safe behavior in the event of LIN bus short-to-ground or LIN bus leakage during low-power mode.

　　Features

　　•Operational from VSUP 6.0V to 18V DC, Functional up to 27V DC, and Handles 40V During Load Dump

　　•Active Bus Waveshaping Offering Excellent Radiated Emission Performance

　　•5.0kV ESD on LIN Bus Terminal•30kΩ Internal Pullup Resistor

　　•LIN Bus Short-to-Ground or High Leakage in Sleep Mode•-18V to +40V DC Voltage at LIN Terminal•8.0µA Standby Current in Sleep Mode

　　•Local and Remote Wake-Up Capability Reported by INH and RXD Terminals

　　•5.0V and 3.3V Compatible Digital Inputs Without Any External Components Required
