MOSFET的驱动芯片

Other Parts Discussed in Thread: LM25101

自己做逆变电路在选驱动芯片有困惑,在选型时,产品选的Half-Bridge Drivers,激励数量有1,2,3driver等不同。

问题1.为什么半桥Half-Bridge Drivers激励数量不是2个?

问题2.看了一个Half-Bridge Drivers,激励数1个(如上图1driver),型号为LM25101,该驱动芯片结构如下,有两个MOSFET为什么激励数不是2个,这款驱动芯片可以驱动几个mosfet?

问题3.驱动芯片如果是2个driver,我做全桥逆变时4个mosfet开关管,2个driver的驱动芯片是可以选全桥4个管子任意2个管子驱动吗,还是说必须是上下桥臂或是上侧两桥臂?
