stk681-320 ON Semiconductor, stk681-320 Datasheet - Page 3

• Manufacturer Part Number: stk681-320
• Description: Thick-film Hybrid Ic Forward/reverse Motor Driver
• Manufacturer: ON Semiconductor

The range of DC operating current lies within the above derating curve in the V CC 1 allowable operating range.
The above motor current I O is valid within the chopping operating range of DC operating.
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.
