IRS2109/IRS21094(S)PbF
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 IN input
• Logic and power ground +/- 5 V offset.
• Internal 540 ns deadtime, and programmable
up to 5 µs with one external RDT resistor (IRS21094)
• Lower di/dt gate driver for better noise immunity
• Shutdown input turns off both channels.
• RoHS compliant
Description
The IRS2109/IRS21094 are high voltage, high
speed power MOSFET and IGBT drivers with de-
pendent high- and low-side referenced output
channels. Proprietary HVIC and latch immune
CMOS technologies enable ruggedized monolithic
construction. The logic input is compatible with stan-
dard 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-con-
duction. 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.
