... 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 Finally, both parts are available in a very compact 9 Ld DFN package to minimize the required PCB footprint ...

... CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. 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 unless otherwise specified ...
