100V, 3A/4A Peak, High Frequency Half-Bridge Drivers

DATASHEET

The ISL2110, ISL2111 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. Peak output

pull-up/pull-down current has been increased to 3A/4A, which

significantly reduces switching power losses and eliminates

the need for external totem-pole buffers in many applications.

been extended to 8VDC. The ISL2110 has additional input

hysteresis for superior operation in noisy environments and the

inputs of the ISL2111, like those of the ISL2110, can now
