International Rectifier IR2109(4)(S) Half-Bridge Driver Data Sheet
The document describes the IR2109(4)(S), a high voltage, high speed power MOSFET and IGBT driver featuring dependent high and low side referenced output channels. It utilizes proprietary HVIC and latch immune CMOS technologies for ruggedized monolithic construction.
Key features include floating channel design for bootstrap operation up to +600V, tolerance to negative transient voltage, and dV/dt immunity. The device supports gate drive supply ranges from 10 to 20V with undervoltage lockout for both channels.
