Short circuit to VDH
A short circuit between SH1 and VDH results in VDS_HS1 = LOW and VDS_LS1 = HIGH when Ishx_PD HB1 and
Ishx_PD HB2 are activated.
SH2 is also pulled up by the short circuit via the motor, so VDS_HS2 = LOW and VDS_LS2 = HIGH.
Similarly, a short circuit of SH2 to VDH results in VDS_HS1/2 = LOW and VDS_LS1/2 = HIGH.
The Figure 24 and Table 27 summarize the results obtained with a short circuit of one output to VDH.
