DESCRIPTION

The AU5783 is a line transceiver being primarily intended for

in-vehicle multiplex applications. It provides interfacing between a

J1850 link controller and the physical bus wire. The device supports

the SAE/J1850 VPWM standard with a nominal bus speed of

10.4 kbit/s. For data upload and download purposes the 4X

transmission mode is supported with a nominal bus speed of

41.6 kbit/s. The AU5783 provides protection against loss of ground

conditions, thus ensuring the network will be operational in case of

an electronic control unit loosing connection to ground potential. Low

power operation is supported through provision of a sleep mode with

very low power consumption. In addition an external voltage

regulator can be turned off via the AU5783 transceiver to further

reduce the overall power consumption. The voltage regulator will be

activated again upon detection of bus activity or upon a local

wake-up event.
