1 Data Sheet FN V, 3A/A Peak, High Frequency Half-Bridge Drivers The ISL20, ISL2 are 00V, high frequency, half-bridge N-Channel power MOSFET driver ICs. They are based on the popular P200, P20 half-bridge drivers, but offer several performance improvements. Peak output pull-up/ pull-down current has been increased to 3A/A, 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 DD operational supply range has been extended to 8VDC. The ISL20 has additional input hysteresis for superior operation in noisy environments and the inputs of the ISL2, like those of the ISL20, can now safely swing to the V DD supply rail.
