Power MOSFET Drivers

The TC4426A/4427A/4428A are improved versions of the earlier TC426/427/428 family of buffer/gate drivers (with which they are pin compatible). They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5 V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4 kV of electrostatic discharge. As MOSFET gate drivers, the TC4426A/4427A/4428A can easily switch 1,000 pF gate capacitances in under 30 ns, and provide low enough impedances in both the ON and OFF states to ensure the MOSFET's intended state will not be affected, even by large transients.TC4426A/4427A/4428A 是较早的 TC426/427/428 缓冲器/栅极驱动器系列（与它们引脚兼容）的改进版本。在其功率和电压额定值范围内的任何条件下，它们都不会闩锁。当接地引脚上出现高达 5 V 的噪声尖峰（任一极性）时，它们不会受到损坏。他们可以接受高达 500 mA 的反向电流（任一极性）被迫返回其输出，而不会造成损坏或逻辑混乱。所有端子均受到全面保护，可防止高达 4 kV 的静电放电。作为 MOSFET 栅极驱动器，TC4426A/4427A/4428A 可以在 30 ns 内轻松切换 1,000 pF 栅极电容，并在导通和关断状态下提供足够低的阻抗，以确保 MOSFET 的预期状态不会受到影响，即使是受到大瞬变的影响.
