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 VDD 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
www.DataSheet4U.com 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.

DESCRIPTION
VDD
HB
Positive supply to lower gate driver. Bypass this pin to VSS.
High-side bootstrap supply. External bootstrap capacitor is required. Connect positive side of bootstrap capacitor to this pin. Bootstrap
diode is on-chip.
HO High-side output. Connect to gate of high-side power MOSFET.
HS High-side source connection. Connect to source of high-side power MOSFET. Connect negative side of bootstrap capacitor to this pin.
HI High-side input.
LI Low-side input.
VSS Chip negative supply, which will generally be ground.
LO Low-side output. Connect to gate of low-side power MOSFET.
EPAD Exposed pad. Connect to ground or float. The EPAD is electrically isolated from all other pins.
