The IC supports 3 channels operating separately or the parallel connection of two channels. For 3th motor application, the power supply for 3th motor is from both VS1 and VS2 pins. In multiple power supply application, although power supply of control logic and motor driver are separated, the voltage of VDD pin must be lager than or equal to the voltage of VS1 and VS2 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: |
