ISL71441M Overview
The ISL71441M is a Radiation Tolerant PWM input 12V Half Bridge GaN FET Driver designed to drive 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 pact and robust GaN FET half-bridge driver. The ISL71441M can interface directly to the ISL73847M dual-phase PWM buck controller...
