For this reason it is not recommended to use the device with channels in parallel. 7.3.3 Cross Current robustness with H-Bridge configuration When BTS7020-2EPA is used as high-side switch e.g. in a bridge configuration (therefore paired with a low-side switch as shown in Figure 21), the maximum slew rate applied to the output by the low-side switch must be lower than | dVOUT / dt |. Otherwise the output stage may turn ON in linear mode (not in RDS(ON)) while the low- side switch is commutating. This creates an unprotected over heating situation for the DMOS due to the cross- conduction current.
