LIN bus interfaces (only for SPSB0815 and SPSB0813)

3.11.1

Features

•

LIN ISO 17987-4/2016 compliant transceiver

•

Designed according to SAE J2962-1 (draft nov. 2017)

•

Meet OEM hardware requirements for CAN and LIN FR-Interfaces (version 1.3 2012)

•

Data rate up to 20 kbit/s

•

GND disconnection fail-safe at module level

•

Off mode: does not disturb network

•

GND shift operation at system level

•

Microcontroller interface with CMOS compatible I/O pins

•

Internal pull-up resistor

•

Transients immunity and ESD according to ISO7637-2, ISO 62215-3 and EN / IEC 61000-4-2.

•

Matched output slopes and propagation delay

•

Wake up behavior according to LIN2.2a and ‘Hardware requirements for LIN, CAN and Flexray interfaces

(version 1.3)

At VSREG > Vpor (that is, VSREG power-on reset threshold), the LIN transceiver is enabled.

The LIN transmitter is disabled in case of the following errors:

•

Dominant TxD_L time out

•

LIN permanent recessive

•

Thermal shutdown 1

–

with thermal sensor “Global” in mode “no cluster”

or with thermal sensor “Th_CL4” in mode “cluster”

•

VSREG overvoltage / undervoltage

•

V1 undervoltage

The LIN receiver is not disabled in case of any failure condition.

(it is reactivated in case of FS by thermal shutdown)
