DRV3901-Q1: DEV_ERR after first trigger

Tool/software:

Dear team, 

My customer would like to use DRV3901-Q1 for their pyro fuse driver. But there is issue like below. 

- Power ON => First Trigger signal operation seems normal but After first trigger, the fault occur and we can see DEV_ERR. Due to DEV_ERR, we can not check register value. 

This issue is maintained even after power off /on. However, after the Reservoir CAP is discharged, it works normally. 

 Can you guess the reason of this issue and why DEV_ERR occurs? Please review this issue and let me know your opinion. 

Thank you.
