Description
The IR7304S is a high voltage, high speed, power
MOSFET and IGBT gate driver with high-side and low-side
referenced output channel. This IC is designed to be used
with low-cost bootstrap power supplies. Proprietary HVIC
and latch immune CMOS technologies have been
implemented in a rugged monolithic structure. The floating
logic input is compatible with standard CMOS or LSTTL
outputs (down to 3.3 V logic). The output drivers feature a
high-pulse current buffer stage designed for minimum driver
cross-conduction. Shoot-through protection circuitry and a
minimum deadtime circuitry have been integrated into this
IC. Propagation delays are matched to simplify the HVIC’s
use in high frequency applications. The floating channels
can be used to drive N-channel power MOSFETs or IGBTs
in the high-side configuration, which operate up to 700 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 unless otherwise stated in the table. The thermal resistance and power dissipation
ratings are measured under board mounted and still air conditions.
