Application with external control
Figure 4 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 SGND. Pin RC is

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.
