求:适于LIN应用的12V到5V的电源转换芯片,最好是freescale的![求助]

如果从节点就选用集成了LIN2.0收发功能的SBC芯片MC33689;如果是主节点,一般这个主节点是CAN-LIN网关,所以可以选用集成了CAN收发器的SBC芯片,低速的有:MC33889,MC33389,高速的MC33989
以下是Freescale Support提供的参考:
As a physical interface you can use one of the following



For CAN:

MC33742, High Speed, Dual 5.0V regulator

MC33389, Low Speed, Dual 5.0V LDO regulator

http://www.freescale.com/files/analog/doc/data_sheet/MC33389.pdf



MC33889, Low Speed, 5.0V LDO regulator

http://www.freescale.com/files/analog/doc/data_sheet/MC33889.pdf





For LIN:

MC33689, 5.0V

http://www.freescale.com/files/analog/doc/data_sheet/MC33689.pdf



MC33399, just physical layer

Currently there is not part that has both LIN and CAN so you will have to use two of the options of above.
