• Diagnostic loop-back mode

• Thermal overload protection

• 14-pin SOIC

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.
