WAKE INPUT PIN (WAKE)
device from the Sleep mode. WAKE is usually connected to
an external switch in the application. The typical wake
thresholds are V
wake-up from both HIGH-to-LOW or LOW-to-HIGH
transitions. When entering into Sleep mode, the LIN monitors
the state of the WAKE pin and stores it as a reference state.
The opposite state of this reference state will be the wake-up
event used by the device to enter again into Normal mode.

with extremely low input current when voltage at this pin is
below 14 V. When voltage at the WAKE pin exceeds 14 V,
input current starts to sink into the device. A serial resistor
should be inserted in order to limit the input current mainly
during transient pulses. Recommended resistor value is
