WebJan 29, 2016 · Your gate driver, when connected to the source of Q1 with an isolated supply, is setting the gate to source voltage directly. It sets the gate-source voltage to either (Vsource + 12V) or (Vsource). Otherwise, you need to know what the source voltage is in order to drive the gate safely. WebAug 6, 2024 · Try the attached high side PMOS driver circuit (LTspice sim). It gives fractionally under 7.5V of gate drive at 8V Vcc, rising to 10V at 12V Vcc, and limits the drive to 12V at 36V Vcc. If built with careful attention to layout, decoupling and parasitics, it should be brutally fast. Sub 100ns edges are possible.
