... MOSFETs in the output stage and a built-in phase signal distribution IC. The incorporation of a phase distribution IC allows the STK672-120-E to control the speed of the motor based on the frequency of an external input clock signal. It supports two types of excitation for motor control: 2-phase excitation and 1-2 phase excitation. It also provides a function for switching the motor direction ...

... It is extremely difficult for SANYO to calculate the internal average power dissipation P D for all possible end product conditions. After performing the above rough calculations, always install the hybrid actual end product and verify that the substrate temperature Tc does not rise above 105°C. STK672-120 ...
