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.
Typical Connection
