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 VDD 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.
