Table 2: MDD20A Absolute Maximum Ratings
*¹ Peak current is limited by the overcurrent protection circuit. Actual current limit is depending
on board temperature. Value shown is at room temperature (25 - 30 degree Celsius).
*² Maximum input voltage can be extended up to 30V by connecting a 10K ohm resistor in
series.

When the PWM operates in extended frequency range, continuous motor current will be
reduced.
