Operating Substrate Temperature, Tc- °C
(The maximum PWM frequency is 50kHz.)
The PWM frequencies in the above graph indicate the ENABLE signal.
The same PWM IO derating curves as those shown above will be obtained when the internal PWM frequency of the
STK681-352-E is used.
Increasing the VCC supply voltage narrows the IO derating curve range, so IO should be set in reference to the above
graph.
The above operating substrate temperature, Tc, is measured immediately when the motor is started.
Since Tc fluctuates due to the ambient temperature, Ta, the motor current value, and continuous or intermittent
operations of the motor current, always confirm this values using an actual set.
The Tc temperature should be checked in the center of the metal surface of the product package.
