Allegro MicroSystems AHV85110 Isolated GaNFET Gate Drivers
Allegro MicroSystems AHV85110 Isolated GaNFET Gate Drivers are self-powered single-channel isolated drivers. These gate drivers are designed to drive GaNFETs in multiple applications and topologies. The AHV85110 gate drivers include a 50ns propagation delay and high peak source/sink capability to efficiently drive GaN FETs in high-frequency designs. These drivers combine the isolated gate driver and power supply into a single, compact package, eliminating the need for an external gate drive auxiliary bias supply or high-side bootstrap. The AHV85110 gate drivers include fast propagation delay and high peak source/sink capability to drive GaN FETs efficiently in high-frequency designs.

Features
- Provide greater power and are more efficient by using 50% of the design footprint (PCB savings)
- Eliminate bootstrap circuits and isolated supplies while minimizing common-mode capacitance, which reduces EMI filter design efforts and improves overall efficiency
- Lower Bill Of Materials (BOM) count and production cost
- Provide a reliable, scalable design process across platforms by removing the need to fully redesign a power module when working with multiple GaN FET suppliers
