UCC27210DPRT

TEXAS INSTRUMENTS  UCC27210DPRT  芯片, 驱动器, 高/低压侧, 4A, 10WSON

Description

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 Miller Plateau of the MOSFET.
