3.2 Dual Driver
The following figure shows the Si82390/1/5/6/7 configured as a dual driver. Note that the drain voltages of Q1 and Q2 can be refer-
enced to a common ground or to different grounds with as much as 1500 Vdc between them.
Figure 3.2. Si82390/1/5/6/7 in a Dual Driver Application
Because each output driver resides on its own die, the relative voltage polarities of VOA and VOB can reverse without damaging the
driver. A dual driver can operate as a dual low-side or dual high-side driver and is unaffected by static or dynamic voltage polarity
changes.
