Single-channel non-isolated gate driver│EiceDRIVER™ 1EDN TDI

综述

具有真差分输入（TDI）的1通道低边 EICICDRIVER ™系列可防止功率 MOSFET 的错误触发

常规低边栅极驱动器 IC 的输入信号电平可以给栅极驱动器 IC 的接地电位提供参考。如果在应用中栅极驱动器 IC 的接地电位发生过度偏移，会导致栅极驱动器 IC 的错误触发。

1EDN7550 栅极驱动器 IC 和 1EDN8550 栅极驱动器 IC 具有真差分输入。它们的控制信号输入基本上与接地电位无关。只有输入触点间的电压差是相关的。这样可以防止功率 MOSFET 的错误触发。
