8.4.2 Current Sense and Regulation (IPROPI)

The DRV8213 device integrates current sensing, regulation, and current sense feedback. The internal current mirror allows the device to sense the output current without an external sense resistor or sense circuitry, thereby reducing system size, cost, and complexity. The current regulation feature allows for the device to limit the output current in the case of motor stall or high torque events and give detailed feedback to the controller about the load current using the IPROPI output. Figure 8-4 shows the IPROPI timings specified in the Electrical Characteristics table.
