资料介绍

UCC27210 和 UCC27211 驱动器是基于广受欢迎的 UCC27200 和 UCC27201 MOSFET 驱动器，但性能得到了显著提升。峰值输出上拉和下拉电流已经被提高至 4A 拉电流和 4A 灌电流，并且上拉和下拉电阻已经被减小至 0.9Ω，因此可以在 MOSFET 的米勒效应平台转换期间用尽可能小的开关损耗来驱动大功率 MOSFET。现在，输入结构能够直接处理 -10 VDC，这提高了稳健耐用性，并且无需使用整流二极管即可实现与栅极驱动变压器的直接对接。这些输入与电源电压无关，并且具有 20V 的最大额定值。

DESCRIPTION  
8-V to 17-V VDD Operating Range, (20-V ABS  
MAX)  
The UCC27210 and UCC27211 Drivers are based on  
the popular UCC27200 and UCC27201 MOSFET  
drivers, but offer several significant performance  
improvements. Peak output pull-up and pull-down  
current has been increased to 4-A source and 4-A  
sink, and pull-up and pull-down resistance have been  
reduced to 0.9 Ω, thereby allowing for driving large  
power MOSFETs with minimized switching losses  
during the transition through the MOSFET’s Miller  
Plateau. The input structure is now able to directly  
handle -10 VDC, which increases robustness and  
also allows direct interface to gate-drive transformers  
without using rectification diodes. The inputs are also  
independent of supply voltage and have a 20-V  
maximum rating.
