描述

The ISL71441SLH is a radiation hardened PWM input 12V half-bridge GaN FET driver that drives low rDS(ON) Gallium Nitride (GaN) FETs for DC/DC switching regulators. An integrated programmable GaN FET gate drive voltage, high-side bootstrap switch, and strong gate drive current provide a compact and robust GaN FET half-bridge driver.

The ISL71441SLH can interface directly to the ISL73847SLH dual-phase PWM buck controller to create a high-efficiency point-of-load regulator to power many of the latest low-voltage high-current FPGA and DSP digital core rails.
