8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The DRV8835 is used in one or two motor control applications. Configure the DRV8835 in parallel to provide

double the current to one motor. The following design procedure can be used to configure the DRV8835 in a

brushed motor application.

8.2 Typical Application

The two H-bridges in the DRV8835 connect in parallel for double the current of a single H-bridge. Figure 6 shows

the connections.
