ISL2100A, ISL2101A

100V, 2A Peak, High Frequency Half-Bridge Drivers

DATASHEET

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.
