1. Speaking of NMOS conduction condition after you just need to VGS> 0 but conduction VS will outweigh the VG, isn't it?

2. We noticed that the whole bridge drive need to bootstrap circuit, this is the reason why

CodePudding user response:

Bridge High lateral Side of the MOS is higher than the supply voltage is needed to open the voltage to open, need to provide the voltage bootstrap
