PRODUCTION DATA
The DRV8235 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 case of motor stall or high load torque events. The IPROPI output provides a current output proportional to the load current. This IIPROPI current can be converted to a VIPROPI output voltage by connecting a suitable resistor RIPROPI from this pin to the circuit ground. The following diagram shows the IPROPI timings specified in the Electrical Characteristics table.
