Figure 6-2: Digital Input Schematic
6.6 5A High-Side Output
Caution
If the VC-EVCC suffers from an unintentional GND contact loss, the freewheeling diode
inside HSOUT4 may lead to an unexpected flow of current from HSOUT4 via its
external load to GND.
As this may lead to undefined behavior of the external load (e.g. a BMS relay), the
usage of HSOUT4 must be considered with care.
If in doubt, please contact the Vector support.
The 5A High-Side Output can be used as a digital output. The FBB is suitable for 24V
applications to drive different loads such as lamps, contactors, relays, or to power other
ECUs.
For diagnostics the Functional Building Block also implements a current and a voltage read
back channel. It can be used as a digital or analog input as a population variant.
Nominal voltage: 24V
Max current: 5A
Voltage drop: ≤ 0.4V
Switching freq.: static on-off / up to 400Hz
