Description

The IRS2184/IRS21844 are high volt-
age, 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 in-
put 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.

Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board
mounted and still air conditions.

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 V

and V

offset rating are tested with all supplies biased at a 15 V differential.

Note 2: Logic operational for V

of -5 V to +600 V. Logic state held for V

of -5 V to -V

. (Please refer to the Design Tip
