Wake-up Source Recognition
A voltage less than the LIN Pre_Wake detection V
receiver.
A falling edge at the LIN pin followed by a dominant bus level V
time period (t
switches from Silent or Sleep Mode to Fail-safe Mode. The VCC voltage regulator is/remains
activated, the INH pin is switched to high, and remote wake-up request is indicated by a low
level at the RXD pin to generate an interrupt for the microcontroller. A low level at the LIN pin
in the Normal Mode starts the bus wake-up filtering time, and if the IC is switched to Silent or
Sleep Mode, it will receive a wake-up after a positive edge at the LIN pin.
A falling edge at the WAKE pin followed by a low level maintained for a certain time period
(t
wake-up request is indicated by a low level at the RXD pin to generate an interrupt in the
microcontroller and a strong pull down at TXD. When the Wake pin is low, it is possible to
switch to Silent or Sleep Mode via pin EN. In this case, the wake-up signal has to be switched
to high > 10µs before the negative edge at WAKE starts a new local wake-up request.
A positive edge at pin KL_15 followed by a high voltage level for a certain time period (> t
results in a local wake-up request. The device switches into the Fail-safe Mode. The extra long
wake-up time ensures that no transients at KL_15 create a wake up. The local wake-up
request is indicated by a low level at the RXD pin to generate an interrupt for the microcon-
troller and a strong pull down at TXD. During high-level voltage at pin KL_15, it is possible to
switch to Silent or Sleep Mode via pin EN. In this case, the wake-up signal has to be switched
to low > 250µs before the positive edge at KL_15 starts a new local wake-up request. With
external RC combination, the time is even longer.
The device can distinguish between a local wake-up request (Wake or KL_15 pins) and a
remote wake-up request (via LIN bus). The wake-up source can be read on the TXD pin in
Fail-safe Mode. A high level indicates a remote wake-up request (weak pull up at the TXD
pin); a low level indicates a local wake-up request (strong pull down at the TXD pin). The
wake-up request flag (signalled on the RXD pin), as well as the wake-up source flag (signalled
on the TXD pin), is immediately reset if the microcontroller sets the EN pin to high (see
