AU5790D14集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

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.
