The two cases show: i) full copper present and ii) with minimal copper present - this being defined as an SM-8 footprint with 1.5mm tracks to the edge of the PCB. For example, on a 5mm x 5mm full copper PCB, the ZHB679 will safely dissipate 2W under DC conditions, taking note of continuous current ratings and voltage limits. Higher powers can be tolerated for pulsed operation, while the shorter pulse widths (1µs and 1ms) being relevant for assessment of switching conditions. The ZHB679 H -Bridge can be modelled within SPICE using the following transistor models configured in the standard H -Bridge topology, as shown in the schematic diagram of this datasheet.
