Data Sheet June 8, 2006 FN6294.0
100V, 2A Peak, High Frequency
Half-Bridge Drivers
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 V
supply rail.

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

NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and
100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
2. Add “-T” suffix for Tape and Reel packing option.
