DATASHEET ISL89400, ISL89401 FN6614 Rev 3.00 100V, 1.25A Peak, High Frequency Half-Bridge Drivers December 4, 2015 The ISL89400, ISL89401 are 100V, high frequency, half-bridge Features N-Channel power MOSFET driver ICs. They are based on the Drives N-channel MOSFET half-bridge popular HIP2100, HIP2101 half-bridge drivers, but offer several performance improvements. The ISL89400 has Space saving DFN package additional input hysteresis for superior operation in noisy DFN package compliant with 100V conductor spacing environments and the inputs of the ISL89401 (like those of the guidelines per IPC-2221 ISL89400) can now safely swing to the V supply rail. Finally, DD Pb-free (RoHS compliant) both parts are available in a very compact 9 Ld DFN package and an 8 Ld SOIC to minimize the required PCB footprint.

Please refer to TB347 for details on reel specifications. 3. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 4.
