Application Notes
To increase system stability, it is suggestion to connect a resistor R
battery power and driver's VDD pin as shown on application circuit.
In multiple power supply application, although power supply of control logic (VDD) and
motor driver (VS1, VS2) are separated for noise reduction, the voltage of VDD, VS1 and
VS2 pins can be expressed by
VDD pin and V(VS) is the voltage of VS1 and VS2 pins.
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:
