IR2103 Description

The Infineon IR2103 is a power MOSFET and IGBT driver with independent high and low-side referenced output channels. Ruggedized monolithic architecture is possible because of proprietary HVIC and latches immune CMOS technology. The logic input works with typical CMOS or LSTTL outputs.

IR2103 Features

• Floating channel designed for bootstrap operation

• Fully operational to +600 V

• Tolerant to negative transient voltage

• dV/dt immune

• Gate drive supply range from 10 to 20 V

• Undervoltage lockout

• 3.3 V, 5 V, and 15 V logic input compatible

• Cross-conduction prevention logic

• Matched propagation delay for both channels

• Internal set deadtime

• High side output in phase with HIN input

• Low side output out of phase with LIN input

IR2103 Applications

• Industrial heating and welding 

• Power tools

• Power Supplies

• Forklifts

• Servo motor

• Robotics

• Home and building automation
