Application Notes
ꢀ
The power dissipated by the IC varies widely with the supply voltage, the output
current, and loading. It is important to ensure the application does not exceed the
allowable power dissipation of the IC package. The recommended motor driver
power dissipation versus temperature is depicted as follows:
