... AN44065A Usage Notes 1. Perform thermal design work with consideration of a sufficient margin to keep the power dissipation based on supply voltage, load, and ambient temperature conditions. (The IC is recommended that junctions are designed below 70% to 80% of Absolute Maximum Rating.) 2. The protection circuit is incorporated for the purpose of securing safety if the IC malfunctions. ...

... AN44065A Usage Notes (continued) motor current will not be less than the current determined by blanking time. Pay utmost attention at the time of minute current control. The graph on the right-hand side shows the relationship between the pulse blanking time and minute current value. The increase or decrease in the motor current is determined by the resistance of the internal winding of the motor. ...
