15 Absolute Maximum Ratings
The maximum ratings may not be exceeded under any circumstances. Operating the circuit at or near
more than one maximum rating at a time for extended periods shall be avoided by application
design.

*) The standstill specification refers to a stepper motor stopped at a high current. Normally, standstill
current should be reduced to a value far below the run current to reduce motor heating.
