I am fairly new to half bridge drivers and understand the concept of a full bridge.  I was looking at building a basic full bridge using 2 half bridge drivers, the driver IC's I was going to use were the international rectifier IRS2004 (datasheet can be found here http://www.irf.com/product-info/datasheets/data/irs2004pbf.pdf).

However the college will have issues ordering them due to USA stock so extra carriage, so I have been looking at the IRS2003 (datasheet can be found here http://www.irf.com/product-info/datasheets/data/irs2003pbf.pdf)

This seems like it will do the task, but I am struggling to understand the timing diagram and the benefit of having the LIN input out of phase by what looks like 180 degrees.

The datasheet states:





My understanding is that if I want to use the irs2003 in a similar fashion to the irs2004 (minus the ShutDown input) , I Feed the same PWM signal into both the HIN and LIN pins?
