Application with external control
Figure 6 shows an application containing a system
ground-referenced control circuit. Pin +LVS can be
connected to the same supply as the external oscillator
control unit and pin LVS is connected to pin SGND.

Pin RC is short-circuited to SGND. The bridge
commutation frequency is determined by the external
oscillator. The bridge disable input (pin BD) can be used to
immediately turn off all four MOSFETs in the full bridge.
