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

• 8- and 14-pin small outline packages
• ±8 kV ESD protection on bus and battery pins
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.
