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. Also, the low end of the VDD operational supply

range has 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 safely swing to the VDD supply rail.
