【文字介紹】

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.
