IRS21814SPBF集成电路（IC）的栅极驱动器规格书PDF中文资料

描述 Description

The IRS2181/IRS21814 are high voltage, high speed power MOSFET and IGBT drivers with independent high-side and low-side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output, down to 3.3 V logi c. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Thefloating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600 V.
