DRV8601 SLOS629B – JULY 2010 – REVISED JANUARY 2012 www.ti.com APPLICATION INFORMATION DRIVING DC MOTORS USING THE DRV8601 The DRV8601 is designed to drive a DC motor (also known as Eccentric Rotating Mass or ERM in haptics terminology) in both clockwise and counter-clockwise directions, as well as to stop the motor quickly. This is made possible because the outputs are fully differential and capable of sourcing and sinking current.

DRV8601 SLOS629B – JULY 2010 – REVISED JANUARY 2012 www.ti.com PSEUDO-DIFFERENTIAL FEEDBACK WITH INTERNAL REFERENCE In the pseudo-differential feedback configuration (Figure 15), feedback is taken from only one of the output pins, thereby reducing the number of external components required for the solution. The DRV8601 has an internal reference voltage generator which keeps the REFOUT voltage at VDD/2.

DRV8601 SLOS629B – JULY 2010 – REVISED JANUARY 2012 www.ti.com PSEUDO-DIFFERENTIAL FEEDBACK WITH LEVEL-SHIFTER This configuration is desirable when a regulated supply voltage for the DRV8601 (VDD) is availble, but that voltage is different than the PWM input voltage (VPWM). A single NPN transistor can be used as a low-cost level shifting solution. This ensures that VIN = VDD even when VPWM ≠ VDD. A regulated supply for the DRV8601 is still recommended in this scenario.

DRV8601 SLOS629B – JULY 2010 – REVISED JANUARY 2012 www.ti.com When driving motors which can sufficiently reject the PWM frequency by themselves, the feedback capacitor may be eliminated. For this example, the output voltage is given by: R VPWM ö æ ´ F VO,DIFF = ç VIN ÷ 2 ø RI è (4) where the only difference from Equation 3 is that the filtering action of the capacitor is not present.
