bus applications.
includes as well as a fast baud rate for test and programming
modes. It has excellent ESD robustness and immunity
against disturbance, and radiated emission performance. It
has safe behavior in case of a LIN bus short-to-ground, or a
LIN bus leakage during low power mode.
POWER SUPPLY PIN (VSUP2)
avoid a false bus message, an under-voltage on VSUP2
disables the transmission path (from TXD to LIN) when V
falls below 6.1 V.
GROUND PIN (GND)
LIN interface do not have significant current consumption on
the LIN bus pin when in the recessive state.
LIN BUS PIN (LIN1, LIN2)
receiver. It is suited for automotive bus systems, and is
compliant to the LIN bus specification 2.1 and SAEJ2602-2.
Driver Characteristics
current thermal shutdown. An internal pull-up resistor with a
serial diode structure is integrated so no external pull-up
components are required for the application in a slave node.
An additional pull-up resistor of 1.0 kΩ must be added when
the device is used in the master node. The 1.0 kΩ pull-up
resistor can be connected to the LIN pin or to the ECU battery
supply.
