Overview

ISL71441SLH Radiation Hardened 12V Half-Bridge GaN FET Driver Datasheet The ISL71441SLH is a Radiation Hardened PWM input 12V Half Bridge GaN FET Driver that drives low rDS(ON) Gallium Nitride 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.
