UCC27210 High/Low Side Driver

Texas Instruments' 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, 4 A sink, and pull-up and pull-down resistance has been reduced to 0.9 Ω, allowing the driving of 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, increasing robustness and allowing 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.
