9.2.1.3 Stall Detection

Some applications require stall detection to notify the microcontroller of a locked-rotor/stall condition. A stall could be caused by one of two things: unintended mechanical blockage or the load reaching an end-stop in a constrained travel path. The DRV8213 supports two methods for determing a stall conditions: hardware stall detection and software stall detection. The RTE package supports hardware stall detection by providing additional pins to configure the response of the device to a stall condition as shown in Figure 9-3. Both DSG and RTE packages support software stall detection by providing the IPROPI analog current sense feedback to the ADC of a microcontroller as shown in Figure 9-1 and Figure 9-3.
