Overview

Description

The ISL73041SEH is a PWM input 12V Half Bridge GaN FET Driver designed to drive low rDS(ON), high Qgs enhance mode Gallium Nitride (eGaN) FETs up to 1.5MHz operation for DC/DC switching regulators. An integrated programmable GaN FET gate drive voltage, high-side bootstrap switch and high gate drive current provide a compact and robust GaN FET half bridge driver.

The ISL73041SEH is designed to interface directly to the ISL73847SEH 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.

The ISL73041SEH is offered in a 16 Ld Ceramic Leadless Chip Carrier (CLCC) hermetic package. It is specified to operate across an ambient temperature range of -55 °C to +125 °C.
