multiplexing
• Bus speed 10.4 kbps nominal
• Drive capability 32 bus nodes
• Low RFI due to output waveshaping with adjustable slew rate
• Direct battery operation with protection against +50V load dump,
jump start and reverse battery
• Bus terminals proof against automotive transients up to
–200V/+200V
• Thermal overload protection
• Very low bus idle power consumption
• Diagnostic loop-back mode
• 4X mode (41.6 kbps) reception capability
• ESD protected to 9 KV on bus and battery pins
• 8-pin SOIC
DESCRIPTION
The AU5780 is a line transceiver being primarily intended for
in-vehicle multiplex applications. It provides interfacing between a
link controller and the physical bus wire. The device supports the
SAE/J1850 VPWM standard with a nominal bus speed of 10.4 kbps.
