AHV85110: Self-Powered Single-Channel Isolated GaNFET Gate Driver with Power-Thru Integrated Isolated Bias Supply

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.
The driver has fast propagation delay and high peak source/ sink capability to efficiently drive GaNFETs in high-frequency designs. High CMTI combined with isolated outputs for both bias power and drive make it ideal in applications requiring isolation, level-shifting, or ground separation for noise immunity.
