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.
