Description
The IRS2108/IRS21084 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 input
is compatible with standard CMOS or
LSTTL output, down to 3.3 V logic. The
output drivers feature a high pulse cur-
