100V, 1.25A Peak, High Frequency
Half-Bridge Drivers
Features
• Drives N-Channel MOSFET Half-Bridge
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 to minimize the required PCB footprint.

NOTES:
1. The ISL89400 and ISL89401 are capable of derated operation at supply voltages exceeding 14V. Figure 22 shows the high-side voltage derating
curve for this mode of operation.
2. All voltages referenced to VSS, unless otherwise specified.
3. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features.
4. For θJC, the “case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379 for details.
