Description
The IRS2108/IRS21084 are high voltage, high speed power MOSFET and IGBT drivers with dependent high- and low-side referenced output channels. Proprietary HVIC and latch immune CMOS 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 an N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600 V.
Specifications and 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 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 LIN input
• Logic and power ground +/- 5 V offset
• Internal 540 ns deadtime, and programmable up to 5 µs with one external RDT resistor (IRS21084)
• Lower di/dt gate driver for better noise immunity
• RoHS compliantApplication Scenarios
This electronic component model, IRS2108DS, can be used in various power MOSFET and IGBT driver applications. It is designed to operate at high voltages up to 600 V and is compatible with different input logic levels (3.3 V, 5 V, and 15 V). The floating channel is specifically designed for bootstrap operation, providing reliable and efficient performance.
