Key benefits of the integrated DRV8x solution:

+ Robust solution, thanks to the integrated protection features

(over-current, over-temp, under-voltage, cross-conduction, etc).

+ Reduced development time, efforts and costs.

+ Reduced PCB space and BOM.

+ Different interfaces and levels of control loop integration.

+ Support of different motors: - Single H-bridge for Brushed DC motors

- Dual H-bridge for Stepper motors

- 3 half-bridges for BLDC and PMSM motors

• The DRV8841 and 8843 are identical except for the bridge logic

• For Brushed DC applications:

– 8841 supports coast via pulling the decay or I0/I1 pins high. Customers typically pick

the 8841 to meet existing design control criteria.

– 8843 supports coast via the IN1/IN2 pins. Customers typically pick the 8843 for new

designs as it requires less control pins.
