DATASHEET ISL2110, ISL2111 FN6295 Rev.7.00 100V, 3A/4A Peak, High Frequency Half-Bridge Drivers Mar 16, 2017 The ISL2110, ISL2111 are 100V, high frequency, half-bridge Features N-Channel power MOSFET driver ICs. They are based on the Drives N-Channel MOSFET half-bridge popular HIP2100, HIP2101 half-bridge drivers, but offer several performance improvements. Peak output SOIC, DFN, and TDFN package options pull-up/pull-down current has been increased to 3A/4A, which SOIC, DFN, and TDFN packages compliant with 100V significantly reduces switching power losses and eliminates conductor spacing guidelines per IPC-2221 the need for external totem-pole buffers in many applications. Pb-free (RoHS compliant) Also, the low end of the V operational supply range has DD been extended to 8VDC. The ISL2110 has additional input Bootstrap supply max voltage to 114VDC hysteresis for superior operation in noisy environments and the On-chip 1W bootstrap diode inputs of the ISL2111, like those of the ISL2110, can now safely swing to the V supply rail.
