6.10 Real Time Clock
An unbuffered real time clock with timer and calendar functions. Alarm and timer functions
can additionally trigger a wake-up signal. The FBB ensures that the wake event can be read
by the µC after wake-up.
6.11 200mA High-Side Output
Caution
If the High Side Outputs of the VC-EVCC are used, measures must be taken to ensure
a load current greater than 15mA (HSOUT0, HSOUT1) respectively 330mA (HSOUT4).
An appropriate load resistor must be calculated depending on the supply voltage.
Otherwise, the VC-EVCC will detect an OpenLoad error which leads to a switch-off of
the High Side Output.
If in doubt, please contact the Vector support.
Digital Output for currents up to 200mA, used to drive small loads or as a status output for
other ECUs. The outputs have various optional configurations. Each of them can be used
as digital or analog inputs as a population variant.
