The ISL71441M 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 ISL71441M is designed to interface directly to the ISL73847M dual-phase PWM buck controller to create a high-efficiency Point-of-Load (POL) regulator to power many of the latest low voltage high current FPGA and DSP digital core rails.

The ISL7144M is offered in a 20 Ld 5mm x 5mm Quad Flat No Lead (QFN) plastic package. It is specified to operate across an ambient temperature range of -55 °C to +125 °C.
