FAN7380 Half-Bridge Gate Driver Features Description Floating Channel Designed for Bootstrapping The FAN7380 is a monolithic half-bridge gate drive IC for Operation to +600V MOSFETs and IGBTs, which operate up to +600V.

Typically 90m A/180m A Sourcing/Sinking Current Fairchild’s high-voltage process and common-mode Driving Capability for Both Channels noise canceling technique give stable operation of high- side driver under high-dv/dt noise circumstances. An
