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