The AHV85111 isolated gate driver is optimized for driving GaN FETs in multiple applications. An isolated dual positive/ negative output bias supply is integrated into the driver device, eliminating external gate drive auxiliary bias supply or high-side bootstrap. The bipolar output rails with adjustable and regulated positive rail improves dv/dt immunity, 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.
