this deadtime should allow for the turn on and turn off time of the transistors, especially when slowing them down with gate resistors. this situation will be present when switching motor direction, or when sophisticated timing schemes are used for se rvo systems such as locked antiphase pwm'ing for high bandwidth operation. application notes bridge drive considerations it is important that the logic used to turn on and off the various transistors allow sufficient "dead time" between a high s ide transistor and its low side transistor to make sure that at no time are they both on. when they are, this is called "shoot-thr ough", and it places a momentary short across the power supply. this overly stresses the transistors and causes excessive noise as we ll. see figure 1. 3 figure 1 rev. b 7/10
