TLE9263QX

LIN Transceiver

11.2

Functional Description

The LIN Bus is a single wire, bi-directional bus, used for in-vehicle networks. The LIN transceivers implemented

inside the TLE9263QX are the interface between the micro controller and the physical LIN Bus. The digital output

data from the micro controller are driven to the LIN bus via the TXD input pin on the TLE9263QX. The transmit

data stream on the TXD input is converted to a LIN bus signal with optimized slew rate to minimize the EME level

of the LIN network. The RXD output sends back the information from the LIN bus to the micro controller. The

receiver has an integrated filter network to suppress noise on the LIN Bus and to increase the EMI (Electro

Magnetic Immunity) level of the transceiver.

Two logical states are possible on the LIN Bus according to the LIN Specification 2.2.

Every LIN network consists of a master node and one or more slave nodes. To configure the TLE9263QX for

master node applications, a resistor in the range of 1 kΩ and a reverse diode must be connected between the LIN

bus and the power supply VSHS.

The different transceiver modes can be controlled via the SPI LIN1 and LIN2 bits.

Figure 33 shows the possible transceiver mode transitions when changing the SBC mode.

LIN OFF Mode

The LIN OFF Mode is the default mode after power-up of the SBC. It is available in all SBC Modes and is intended

to completely stop LIN activities or when LIN communication is not needed. In LIN OFF Mode, a wake-up event

on the bus will be ignored.

Behavior after SBC Restart Mode - not coming from SBC Sleep Mode due to a wake up of the respective transceiver:

If the transceivers had been configured to Normal Mode, or Receive Only Mode, then the mode will be changed to Wake

Capable. If it was Wake Capable, then it will remainWake Capable. If it had been OFF before SBC Restart Mode, then it

will remain OFF.

Behavior in SBC Development Mode:

LIN default value in SBC INIT MODE and entering SBC Normal Mode from SBC Init Mode is ON instead of OFF.
