TLE 6244X
1.13 Parallel Connection of Power Stages
The power stages (PS) which are connected in parallel have to be switched on and off simultaneously.
The corresponding SPI-Bits SCONx have to be in the same register (see page 15), when the PS are
serial controlled via SPI.
In case of overload the ground current and the power dissipation are increasing. The application has to
take into account that all maximum ratings are observed (e.g. operating temperature T
J
and total
ground current I
GND
, see page 36, 37).
Max. number of parallel connections: 3
The following statements apply to PS within the same TLE6244X
The max. short circuit shutdown threshold of the parallel connected PS is the summation of the corre-
sponding max. values of the PS (I
SC,OUTx
+ I
SC,OUTy
+....
).

Max. Clamping Energy
