Hi Ivy,
Thank you for your question.
The open load detection time is maximum 200 ms for DRV8889-Q1. This means that If the winding current in any coil drops below the open load current threshold (IOL: 30mA) and the ITRIP level set by the indexer, and if this condition persists for more than the open load detection time (tOL: 200ms), an open-load condition is detected. This time may be less than 200ms but it varies for each devices. The typical value is not reported but it can be between 80ms to 200ms.
Best regards,
Mojtaba
