DRV8832: DRV8832 fault triggering with current limit

Part Number:DRV8832

Hi team,

I would like to know DRV8832 regards to the fault triggered by current limit condition.  

I am using DRV8832EVM to verify whether the fault can triggered by current limit condition. For the experiment, I stop the motor by hand while it’s rotating and the current limit condition was considered keep happening on DRV8832 (current limits set to around 400mA). As below description in datasheet, when fault condition persists for more than 275ms a fault signal should be triggered. But in fact, we can’t observe the fault was triggered. Does team has the application curve while current limit happen and fault triggered? Is there anything customer missed?

Here is the test condition:

1. 5V apply to VCC
2. VSET is about 1.45V

Motor spec: 5V/500mArms (7ohm wire resistance)

 Regards,

Alex
