IRS21844MPBF
Description
The IRS21844MPBF is a high voltage, high speed power MOSFET and IGBT drivers with dependent high
and lowꢀside 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 current buffer stage designed for minimum driver
crossꢀconduction. The floating channel can be used to drive an Nꢀchannel power MOSFET or IGBT in the
highꢀside 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.

All supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply.
Recommended Operating Conditions
The input/output logic timing diagram is shown in Figure 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.
