In addition to a wake-up from sleep mode via the bus lines CANH or CANL it is also
possible to wake-up the TLE6263 from low power mode via the wake-up inputs WK1 and
WK2. The wake-up inputs are sensitive to a transition of the voltage level, either from
high to low or the other way round. They are active in all operation modes. In the normal
mode the current logic level at WK1/2 is monitored via the SPI (see table 4 and 6).
A positive or negative voltage edge at WK1/2 in V
immediately results in setting the output RxD low to signal a wake-up. After a wake-up
via WK1/2 the transmission of the SPI diagnosis word in the V

each transmission. As long as IBIT1 is set high or the internal wake flip-flop is reseted
respectively, in the V
up event via the CAN-bus or the wake-up inputs.
Further to the continues sensing at the wake-up inputs a cyclic sense feature is possible.
When the OUTHS cyclic sense feature is selected via the SPI IBIT 4 the high side switch
as well as the WK1/2 inputs are periodically activated by the TLE6263 in the sleep and
V
When switching the TLE6263 into sleep mode (cyclic sense feature activated) the
voltage level at the wake-inputs is sensed 2 times to initialize the reference voltage.
Should this initialisation fail (2 samples are unequal) the device is automatically set in
V
mode now directly from the V
reseted by the IBIT 1.

Like the reset output, the interrupt output is a low active output. It is used to monitor low
voltage conditions at the sense input in normal mode and stand-by mode (see table 8).

OUTHS can be periodically switched on by the TLE6263 itself. In order to activate this
cyclic sense feature the SPI IBIT 4 has to be set high. The auto-timing period then is typ.
