AHV85110 Product Video

The AHV85110 isolated gate driver is optimized for driving GaNFETs in multiple applications and topologies. An isolated output bias supply is integrated into the driver device, 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 common-mode (CM) capacitance. It also allows the driving of a floating switch in any location in a switching power topology.
