Single wire CAN transceiver
AU5790
FEATURES
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
• 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
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.
• 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
