Application Notes In multiple power supply application, the voltage of VDD pin must lager than or equal to the voltage of VS pin. 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: Power Dissipation-Temperature Power Dissipation ( mW ) 700 600 500 400 300 200 100 0 0 25 50 75 100 125 Ambient Temperature ( ℃ ) ST1151A_A03.doc Version：A.03 Page：4 點晶科技股份有限公司 ST1151A SILICON TOUCH TECHNOLOGY INC.
