<Hybrid IC Internal Average Power Dissipation>
The devices with the largest power dissipations within the STK672-010 are the current control devices, the regenerated
current diodes, the current detection resistors, and the pre-drive circuits.
The power dissipations for each of the excitation modes are given by the following formulas.

The times t1, t2, and t3 are shown in the figure below.
t1: The time for the winding current to reach the set value
t2: The time in the fixed current chopping region
t3: The time from the point where the phase input signal is cut to the point where the regenerated reverse
power is dissipated.
