AU5783 General 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.

AU5790 General Description

The AU5790 is a line transceiver, primarily intended for in-vehicle multiplex applications. The device provides an interface between a CAN data link controller and a single wire physical bus line. The achievable bus speed is primarily a function of the network time constant and bit timing, e.g., up to 33.3 kbps with a network including 32 bus nodes. The AU5790 provides advanced sleep/wake-up functions to minimize power consumption when a vehicle is parked, while offering the desired control functions of the network at the same time. Fast transfer of larger blocks of data is supported using the high-speed data transmission mode.

AU5790 Features

• Supports in-vehicle class B multiplexing via a single bus line with ground return
• 33 kbps CAN bus speed with loading as per J2411
• 83 kbps high-speed transmission mode
• Low RFI due to output waveshaping
• Direct battery operation with protection against load dump, jump start and transients
• Bus terminal protected against short-circuits and transients in the automotive environment
• Built-in loss of ground protection
• Thermal overload protection
• Supports communication between control units even when network in low-power state
• 70 µA typical power consumption in sleep mode
• 8- and 14-pin small outline packages
• ±8 kV ESD protection on bus and battery pins
