INTEGRATED CIRCUITS AU5790 Single wire CAN transceiver Product data Supersedes data of 2001 Jan 31 IC18 Data Handbook 2001 May 18 Philips Semiconductors Philips Semiconductors Product data Single wire CAN transceiver AU5790 FEATURES Supports in-vehicle class B multiplexing via a single bus line with ground return 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. 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 s...
