modes. It has excellent ESD robustness and immunity
against disturbance, and radiated emission performance. It
has safe behavior when a LIN bus short-to-ground, or a LIN
bus leakage during LP Mode.

compliant to the LIN bus specification 2.1 and SAEJ2602-2.
Driver Characteristics
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.

The physical interface is dedicated to automotive LIN sub-
The interface has 20 kbps and 10 kbps baud rates, and
Digital inputs are related to the device VDD pin.
The VSUP/2 pin is the supply pin for the LIN interface. To

The LIN pin represents the single-wire bus transmitter and
The LIN interface is only active during Normal Mode.
The LIN driver is a LS MOSFET with internal over-current
The LIN interface have two operational modes, Transmit
In the TXD/RXD Mode, the LIN bus can transmit and
