Hello! I`ve got some problems in my design. I have Totem-pole switching circuit topology, upper MOSFET (high-side) I open by the driver applying 15V to the gate, but how can I open the lower MOSFET (low-side)? As I know we need gate to source potential, but there is negative polarity power supply on low-side transistor source (not GND). Please help with the solution.
