ISL2110, ISL2111 - Datasheet - 100V High Frequency Half-Bridge Drivers

Nov 2, 2026

Uploaded by 658056

ISL2110 and ISL2111 are 100V high-frequency half-bridge N-channel power MOSFET driver ICs based on the HIP2100/HIP2101 family, with improved peak pull-up/pull-down current (3A/4A) to reduce switching losses. The low end of the VDD operating range is extended to 8V, with ISL2110 adding input hysteresis for noisy environments. Features include bootstrap supply support, on-chip bootstrap diode, fast propagation for multi‑MHz operation, and drive compatibility with CMOS (ISL2110) or 3.3V/TTL (ISL2111) thresholds. Applications span telecom half/full-bridge DC/DC converters, forward converters, active-clamp forward converters, and Class-D audio amplifiers.

DATASHEET | ISL2110, ISL2111
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 DD 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 V DD supply rail.
