Texas Instruments  UCC27211ADRMT

The UCC27211A driver is based on the popular UCC27201 MOSFET drivers; but, this device offers several significant performance improvements. Peak output pullup and pulldown current has been increased to 4-A source and 4-A sink, and pullup and pulldown resistance have been reduced to 0.9 Ω, and thereby allows for driving large power MOSFETs with minimized switching losses during the transition through the Miller Plateau of the MOSFET. The input structure can 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.
