PRODUCTION DATA
"Steady-state" conditions assume that the motor driver operates with a constant average current over a long period of time. The figures in this section show how RθJA and ΨJB (junction-to-board characterization parameter) change depending on copper area, copper thickness, and number of layers of the PCB. More copper area, more layers, and thicker copper planes decrease RθJA and ΨJB, which indicate better thermal performance from the PCB layout.
