Description

The ISL2100A, ISL2101A 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 ISL2100A has additional input hysteresis for superior operation in noisy environments and the inputs of the ISL2101A, like those of the ISL2100A, 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.
