MD111 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 800 750 700 650 600 550 500 450 400 350 300 250 200 150 100 50 0 0 Power Dissipation ( mW ) SOP8 MSOP8 Ambient Temperature ( ℃ ) 25 50 75 100 125 SP-MD111-A.001(Only For Toy Driver) Page：4 Version：A.001 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC.
