Product data sheet
7.3.1 Remote wake-up via the LIN bus
7.3.2 Wake-up via SLPx_N
7.3 Transceiver wake-up
7.4 Operation during automotive cranking pulses
7.5 Operation when supply voltage is outside specified operating range
A falling edge on pin LINx followed by a LOW level maintained for t
a rising edge on pin LINx triggers a remote wake-up (see
the time period t

If SLPx_N is held HIGH for t
Normal mode.
TJA1022 remains fully operational during automotive cranking pulses because the LIN
transceivers are fully specified down to V

cannot be guaranteed to remain within the operating ranges specified in

If the input level on pin TXDx is HIGH, the LIN transmitter output on pin LINx will be
recessive.
If the input level on pin LINx is recessive, the receiver output on pin RXDx will be
HIGH.
If the voltage on pin V
LIN network pull-up resistance should be greater than 680  and the total LIN network
capacitance should be less than 6.8 nF to ensure reliable LIN data transfer.
If the voltage on pin V
the active LIN transmit path(s) is interrupted and both LIN outputs will be recessive.
The previously active LIN transmit path(s) is switched on again when V
