Description
The IRS2108/IRS21084 are high volt-
age, high speed power MOSFET and
I
GBT drivers with dependen
t 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 cur-
rent 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.
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 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

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
Note 1: Logic operational for VS of -5 V to +600 V. Logic state held for VS of -5 V to -VBS. (Please refer to the Design Tip
DT97-3 for more details).

Recommended Operating Conditions
The input/output logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the
recommended conditions. The VS and VSS offset rating are tested with all supplies biased at a 15 V differential.
