7.2.1.1 Design Requirements

When selecting the gate driver device for an end application, some design considerations must be evaluated in order to make the most appropriate selection. Following are some of the design parameters that should be used when selecting the gate driver device for an end application: input-to-output configuration, the input threshold type, bias supply voltage levels, peak source and sink currents, availability of independent enable and disable functions, propagation delay, power dissipation, and package type. See the example design parameters and requirements in Table 7-1.
