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.

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 uA typical power consumption in sleep mode
• 8- and 14-pin small outline packages
• +- 8 kV ESD protection on bus and battery pins
