DC Motor Control with IR7304S driver and CoolMOS™

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.

The 600V CoolMOS™ C6 offers a series extremely low conduction and switching
losses and can make switching applications more efficient, more compact, lighter
and cooler.
