IRS44273L
Description
The IRS44273L is a low voltage, power MOSFET and IGBT non-inverting gate driver. Proprietary latch immune
CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard
CMOS or LSTTL output. The output driver features a current buffer stage.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. The device
may not function or not be operable above the recommended operating conditions and stressing the parts to
these levels is not recommended. In addition, extended exposure to stresses above the recommended operating
conditions may affect device reliability. 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.
