3.6 Power outputs

2.2A/45V

OUT9...OUT14

In case of open input (parallel con-

trol) or missing power supply the

power stage is switched off. Paral-

lel connection of power stages is

possible.

For OUT11... OUT14

Above this limit short circuit to

UBatt is detected. For the duration

of the shutoff delay time tVoff (see

3.6.4) the output current is limited

to approximately this value. If the

short circuit condition is still

present after tVoff, the outputs

OUT11...OUT14 are switched off.

An error is stored after tDiag (see

3.11.4).

The same is true for OUT9,

OUT10 if the static current limita-

tion is not enabled.

Between -40°C and 150°C an

approximately linear characteristic

line can be assumed.

Between 17V

≤ UUBatt ≤ 21V, the

short circuit shutdown threshold is

switched for OUT11..14
