DRV8834: nFault while SLEEP state

$

Hello,

I am using DRV8834 driver along with a stepper motor. I also use the SLEEP state of this driver. According to the datasheet I put the device in SLEEP state by driving the nSLEEP pin low. But for me it's interesting to know if the driver is in SLEEP state and the H-Bridge is disabled effectively. On oscilloscope I can see when the nSLEEP is set from high to low the nFAULT turns from high to low for around 1 ms. But after this 1 ms I could not differ between driver is in SLEEP state or not. Does the driver always drive the nFAULT pin for only around 1 ms when turning into SLEEP state. Is there a range of time perhaps 0.9 ms upto 1.1 ms? Is there an other way to identify whether the driver is in SLEEP state or not?

Thanks in advance for your help.

Torsten
