Description
The IZI-GaN is a single-channel Isolated Intelligent GaN switch with integrated driver and floating power supply. This device uses VDDTECH’s proprietary double capacitive isolation technology for multiple channels digital and analog isolators and an integrated floating DCDC power supply. It also includes programmable features such as GaN drive strength, desaturation detection and half-bridge cross-conduction dead-time. For half-bridge operation, IZI-GaN includes a fail-safe cross-conduction and optional ZVS feature. All internally needed decoupling capacitors are integrated making the device very easy to use with a true zero-passives BOM.
