AHV85110 Overview
The AHV85110 isolated gate driver is optimized for driving GaN FETs in multiple applications and topologies. An isolated output bias supply is integrated into the driver, eliminating the need for any external gate drive auxiliary bias supply or high-side bootstrap. This greatly simplifies the system design and reduces EMI through reduced total mon-mode (CM) capacitance.
