4 Operational / Limiting Ratings
The operational ratings show the intended / the characteristic range for the values and should be
used as design values. An operation within the limiting values is possible, but shall not be used for
extended periods, because the unit life time may be shortened. In no case shall the limiting values be
exceeded.

Table 4.1: Operational / Limiting Ratings
*) At supply voltages below 12V, maximum motor current linearly decreases down to about 0.5A at
9V. To be sure to be outside this area when using the EVALboard, use at least 13V supply voltage,
due to voltage drop in the reverse polarity protection.
4.1 Power supply requirements
The power supply should be designed in a way, that it supplies the nominal motor voltage at the
desired maximum motor current. In no case shall the supply value exceed the upper / lower voltage
limit. To be able to cope with voltage which might be fed back by the motor, the supply should
provide a sufficient output capacitor, additionally a 39V suppressor (zener-)diode may be used.
