IRS2108SPBF

The IRS2108 is high voltage, high speed power MOSFET and IGBT drivers with dependent high and low-side referenced output channels. Proprietary HVIC and latch immuneCMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output, down to 3.3 V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive anN-channel power MOSFET or IGBT in the high-side configuration which operates up to 600 V.

• 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 V to 20 V
• Undervoltage lockout for both channels
• 3.3 V, 5 V, and 15 V input logic compatible
• Cross-conduction prevention logic
• Matched propagation delay for both channels
• High-side output in phase with HIN input
• Low-side output out of phase with input
• Logic and power ground +/- 5 V offset
• Internal 540 ns deadtime, and programmable up to 5µs with one external RDT resistor (IRS21084)
• Lower di/dt gate driver for better noise immunity
• RoHS complaint
