100V, 1.25A Peak, High Frequency
Half-Bridge Drivers
The ISL89400, ISL89401 are 100V, high frequency,
half-bridge N-Channel power MOSFET driver ICs. They are
based on the popular HIP2100, HIP2101 half-bridge drivers,
but offer several performance improvements. The ISL89400
has additional input hysteresis for superior operation in noisy
environments and the inputs of the ISL89401 (like those of
the ISL89400) can now safely swing to the V_DD supply rail.
Finally, both parts are available in a very compact 9 Ld DFN
package and an 8 Ld SOIC to minimize the required PCB
footprint.

NOTE: 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.
