IRS2890DS - half-bridge gate driver

Product Announcement from Infineon Technologies AG


The IRS2890D provides integrated over-current protection (OCP), fault reporting, and bootstrap functionality. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or TTL outputs to 3.3 V, 5 V, and 15 V logic levels.

The output drivers feature a high-pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high side configuration which operate up to 600 V. Propagation delays are matched to simplify the HVIC’s use in high frequency applications
