2.1

overcurrent (OCD) threshold setting

The device integrates two overcurrent protection circuits with adjustable threshold, one for
each full bridge.

The overcurrent threshold is set through the R9 (bridge A) and R8 (bridge B) resistors, as
indicated in

Figure 3: "Overcurrent threshold versus resistor value (no paralleling)"
