TC4427A中文资料Dual 1.5 A MOSFET Gate Driver数据手册Microchip规格书

描述 Description

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.
